Solving Equations

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

-10(2m + 1) = - 50

• m = -7

• m = 20

• m = 5

• m = 2

6p + 10 - 3p = 37

• p = 9

• p = -5

• p = 7

• p = 8

What is the first step to solve this equation?

5x + 6 = 10 + 3x + 4x 

• Add 4x to both sides of the equation

• Combine the terms 3x and 4x on the same side of the equation

• Add 5x and 6 to get 11x

• Combine the terms 5x and 3x and 4x to get 12x

Solve for x:

 $5x=25$  

• x = 6

• x = 5

• x = 4

• x = 50

Solve for y:

 $12-6y=24$  

• y = -1

• y = -2

• y = -3

• y = -4

Which of the following is equivalent to -9(2g - 3) ?

• 18g + 27

• -18g + 27

• -18g - 27

• 18g - 27

Solve for the given variable:

5k + 9 = 19

• k = 3

• k = -5

• k = 2

• k = 6

Solve for k:

 $5k-4=-2k+3$  

• k = 1

• k = 2

• k = 3

• k = 4

(w + 6) 2 = 20

• w = 8

• w = -7

• w = 4
