Solve Equation Review

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5
• Subtract 5
• Multiply by 7
• Subtract 7

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

Solve for w:
-6w + 1 = -11

• 2
• 1.2
• 12
• -2

Solve:
-4x = 24

• 20
• -20
• 6
• -6

Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations
• math
• variable
• PEMDAS

19  + a  =  -50

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

m - 8 = -5 

• m = 13
• m = -13
• m = 3
• m = -3

• x = 20
• x = 7
• x = 10
• x = 3

Solve for x. 2x + 18 - 1 = 33

• x = 7

• x = 25

• x = 8

• x = 21

-20 = -4x - 6x

• x = 2

• x = -2

• x = -10

• x = 10
