Example Question #11 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
Solve for :
Subtract from both sides:
Your result should be:
Example Question #11 : One Step Equations
Solve for :
Subtract 23 from both sides:
Your result should be:
Example Question #12 : One Step Equations
Solve for :
Divide both sides of the equation by 3:
Example Question #13 : One Step Equations
Solve the following:
Since both numbers are the same sign (negative), we can add them.
Remember to keep the sign! In this case, the answer is negative.
Example Question #14 : One Step Equations
Solve for
In order to isolate on one side, we add 8 to both sides.
This gives us:
Example Question #15 : One Step Equations
Solve.
Because the signs are different (63 is negative, 15 is positive) we can subtract:
Remember: the largest number always keeps its sign!
Example Question #16 : One Step Equations
Solve for :
To isolate , we must move all other numbers to the right hand side. Therefore, we must divide both sides by 4.
Example Question #18 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
Solve for :
To isolate , we must subtract 8 from both sides:
Example Question #17 : One Step Equations
Solve the following equation:
In order to solve this equation, you have to isolate the variable to one side by reversing the operations done to it. Whatever is done on one side of the equals sign must be done on the other side of the equals sign as well. When the variable is by itself, it will be defined as whatever is left on the other side of the equals sign, and the equation is solved.
Subtract from each side.
Example Question #21 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
