2x - 3 + 4x = 27

• 12

• 4

• 5

• 15

Solve for x.

-3-3x=12

• x=4

• x=3

• x=-5

• x=12

A wise man once said, "400 reduced by twice my age is 260." What equation represents how old the man is?

• 260-2a=400

• 400-260=2a

• 2a-400=260

• 400-2a=260

Solve for a.
\frac{a}{4}=-3

• a=-12

• a=3/4

• a=16

• a=-1

• y=-28

• y=-1

• y=7

• y=-7

3(x-4)= 36

• x= 7

• x= 4

• x= 10

• x=8

Translate the statement into an equation:

Five less than a number is 6

• n - 5 = 6

• 5 - n = 6

• 6 - 5 = 1

Which equation has x=9 as a solution

• 4 + x = 12

• 5x = 45

• 2x = 20

• x + 7 = 26

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5

-(n - 8) = -2

• 6

• 10

• -10

• -6
