Example Questions
Example Question #27 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
Solve for 
To get y by itself, you must subtract 7 from both sides
which simplifies to
Example Question #25 : One Step Equations
Solve for 
To get x by itself, you must add 4 to both sides of the equation
which simplifies to
Example Question #29 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
Solve for 
To get y by itself, you must multiply both sides of the equation by 3
which simplifies to
Example Question #30 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
Solve for 
To get z by itself, you must subtract 11 from both sides
which simplifies to
Example Question #31 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
Solve for 
To get y by itself, you must add 7 to both sides of the equation
which simplifies to
Example Question #31 : One Step Equations With Integers
Solve for 
Add 2x to each side to get all variables on one side:
Example Question #32 : One Step Equations With Integers
Solve for 
To isolate the variable "s" from the expression 32s, divide both sides of the equation by 32. 128/32=4, so s=4
Example Question #33 : One Step Equations With Integers
Solve for 
Add 3625 to each side to isolate y. This gives you the answer 5024
Example Question #34 : One Step Equations With Integers
Solve:
To solve for 
Example Question #35 : One Step Equations With Integers
solve for 
None of the other answers.
To solve for x you simply isolate it on one side of the equation. To do this, apply the opposite operations to manipulate the equation.
Subtract 15 from both sides:
The red terms canceled.
We just subtract as normal on the right side.
