Example Question #42 : Single Variable Algebra
Solve for .
Multiply both sides by . When multiplying with a negative number, our answer is negative.
Divide both sides by . When dividing with another negative number, our answer is positive.
Example Question #202 : Sat Subject Test In Math I
Solve for .
Square both sides to get rid of the radical.
Subtract on both sides.
Example Question #203 : Sat Subject Test In Math I
Solve for .
Square both sides to get rid of the radical.
Multiply on both sides.
Example Question #201 : Sat Subject Test In Math I
Solve for .
We take the square root on both sides. We also need to consider the negative answer since two negatives multiplied together is positive.
Example Question #205 : Sat Subject Test In Math I
Solve for .
This is a quadratic equation. We can solve by factoring. We need to find teo terms that add to the b term but also multiply to get the c term.
Solve individually.
Add to both sides.
Add to both sides.
Example Question #42 : Single Variable Algebra
Solve for .
Take the square root on both sides. Remember to account for a negative square root.
We will treat as two different equations.
Subtract on both sides. When adding another negative number, we treat as a sum and add a minus sign in the end.
Subtract on both sides. Since is greater than and is negative, our answer is negative. We treat as a subtraction problem.
Example Question #43 : Single Variable Algebra
Solve for .
Let's subtract on both sides. It will be easier to square both sides to get rid of the radical.
This is recognition of a quadratic equation.
We need to find two terms that multiply to the c term but add up to the b term.
Solve individually for zero.
Add on both sides.
Add on both sides.
We need to check our answers.
If , then
If , then
Clearly, doesn't work so our final answer is .
Example Question #41 : Solving Equations
Solve for .
This is a one step, one variable problem. This means we want to isolate x on one side of the equation with all other constants on the other side. To do this perform the opposite operation to manipulate the equation
Subtract on both sides. Since is greater than and is negative, our answer is negative.
We treat as a subtraction problem.
Example Question #44 : Solving Equations
Solve for .
This is a two step, one variable problem. This means we want to isolate x on one side of the equation with all other constants on the other side. To do this perform the opposite operation to manipulate the equation
Subtract on both sides.
Multiply on both sides.
Example Question #45 : Solving Equations
Solve for .
This is a one step, one variable problem. This means we want to isolate x on one side of the equation with all other constants on the other side. To do this perform the opposite operation to manipulate the equation
Add on both sides.
