One Two Step Equation

19  + a  =  -50

• a = -950

• a =  -69

• a = -31

• a = -50/19

Solve for variable x in the following equation:

11 = 3x + 8x

• x = 1

• x = 2

• x = 3

• x = 4

8r = 32

• 4

• 318

• 24

• 40

3n = 39

• 117

• 36

• 12

• 13

4x+1=9

• 1

• 2

• 3

• 4

5x+3=53

• 5

• 10

• 12

x - 62 = 123

How should you show your work to isolate the variable (x) and solve the equation?

• Add 62 to each side.

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

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

how would you solve this equation: 9x=153? 

• multiply

• divide

• add

• subtract
