Step by Step Two Step Equation

What is the first step to solving the equation \(4x\ +\ 30\ =\ 110\) ?

• add 30 to both sides

• subtract 30 from both sides

• multiply both sides by 30

• divide both sides by 30

What is the next step to solve the equation 4x=80?

• add 4 to both sides of the equation

• subtract 4 from both sides of the equation

• multiply both sides of the equation by 4

• divide both sides of the equation by 4

Solve for a

• a= -2

• a= -6

• a= 3

• a= 15

5x + 4 = −6

• 2

• -2

• 10

• 15

2x + 6 = 14

• x = 4

• x = 10

• x = -4

• x = 3

Solve for w:
-6w + 1 = -11

• 2

• 1.2

• 12

• -2

WRITE AN EQUATION
You bought a $5 magazine and four
erasers. You spent a total of $25. How
much did each eraser cost?
