Example Question #451 : How To Solve One Step Equations
Solve the equation:
In order to solve for x, we will need to square both sides.
Simplify both sides.
However, if we substitute back into the original equation, we will only find that positive three is a true solution, and not negative three.
The answer is:
Example Question #452 : How To Solve One Step Equations
Solve the equation:
To isolate the x-variable, divide by six on both sides of the equation. This is similar to multiplying by one-sixth on both sides.
Simplify both sides.
The answer is:
Example Question #453 : How To Solve One Step Equations
Solve the equation:
In order to isolate the x-variable, multiply by on both sides.
Simplify both sides of the equation. On the right side, multiply the whole number to the numerator.
The answer is:
Example Question #454 : How To Solve One Step Equations

Solve for
To solve for we multiply both sides by 3.
And we get
Example Question #457 : How To Solve One Step Equations
Solve for .
To solve, isolate the variable on one side of the equation with all other constants on the other side. Do this by performing the opposite operations.
Subtract on both sides.
Example Question #458 : How To Solve One Step Equations
Solve for .
To solve, isolate the variable on one side of the equation with all other constants on the other side. Do this by performing the opposite operations.
Subtract on both sides.
Since is greater than and is negative, our answer is negative. Therefore, we treat as a subtraction problem.
