• variable

In the expression 3m + 8, the number 3 is called the ____________.

• variable

• constant

• coefficient

• answer

Distribute 5(b - 2) and you get . . .

• 5b - 2

• 5b - 10

• 5b + 10

• 3b

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

What is the first step in solving for w in the equation 3w + 5 = 14?

• Add 5 to both sides of the equal sign

• Divide by 3 on both sides of the equal sign

• Subtract 5 from both sides of the equal sign

• Multiply by 3 on both sides of the equal sign

The first step to solving the equation g - 3 = -12 is to . . .

• divide by -3 on both sides of the equal sign

• multiply by -3 on both sides of the equal sign

• subtract 3 on both sides of the equal sign

• add 3 on both sides of the equal sign

Solve the equation:
-5x = 25

• x = 20
• x = -20
• x = -5
• x = 5

19  + a  =  -50

• a = -950
• a =  -69
• a = -31
• a = -50/19

3x - 5 = -26

• x=-21

• x=21

• x=-7

• x=61

Solve for x:
12 = 20x - 18

• 1
• -2
• -1
• 2
