STAAR Solving Equations

Solve the equation
16 = -6x + 4x - 2

• x = 9

• x = -6

• x = -9

•  = 6

Solve for d:
-7(6 + d) = 49

• 13

• 1

• -1

• -13

Solve the following equation.
4x + 3 = -5

• 1/2

• -1/2

• -2

• 2

Solve for x.

• 55

• 60

• 15

• 35

What is the error?

• Adding 2x to 3x

• Subtracting 5 from both sides

• Adding 2x to -2x

• Dividing by 5 on both sides

What would be the best first step to solving the equation in one step?

• multiply both sides by ³/₂ 

• divide both sides by 3

• multiply both sides by 3

• subtract ²/₃  from both sides

solve for x

• 5

• -25

• 15

• 1/5

Solve for x 

• x = 6

• x = 25

• x = 28
