Solve one-step equations

To solve for a variable, use inverse operations to undo the operations in the equation. Be sure to do the same operation to both sides of the equation.

Learn with an example

🔔 Solve for r.

r − 4 = 4

r =___

Solve.

r − 4 = 4

r − 4 + 4 = 4 + 4 Add 4 to both sides

r = 8 Simplify

🔔 Solve for y.

7 = y − 1

y =______

Solve.

7 = y − 1

7 + 1 = y − 1 + 1 Add 1 to both sides

8 = y Simplify

🔔 Solve for j.

j/2= 2

j =_____

Solve.

j/2 = 2

j/2 . 2 = 2 . 2 Multiply both sides by 2

j = 4 Simplify
