Solve for a.

15 = 2a + 7

• a=2

• a=4

• a=12

• a=14

Solve for x.
 $\frac{x}{4}+11\ =\ 20$  

• x = 9

• x = 36

• x = 9/4

• x = 31/4

Solve for x.

2(x + 15) = -6

• x = -10.5

• x = -18

• x = 18

• x = 10.5

Solve for x.

3(x + 2) = 21

• 4

• 5

• 6

• 7

Solve for x.

2(x+3) = 20

• 5

• 6

• 7

• 10

 $\frac{x}{2}\ +\ 6\ =\ 8$  

Solve for x.

• 5

• 7

• 4

• 10

3(x+4) = 27

• 11

• 12

• 5

• 10

Answer explanation

3(x) + 3(4) = 27

3x + 12 = 27

-12 -12

3x = 15

x = 5

5(2x + 8 ) = 70

• 4

• 6

• 1

• 3

Answer explanation

5(2x) + 5(8) =70

10x + 40 = 70

-40 = -40

10x = 30

x = 3
