2 step equations

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

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.

Figure out what n equals in this equation:
6n + 4 = -26

• n=-6
• n= -5
• n= 8
• n= -4

The goal of solving two-step equations is to:

• francine
• Find the coefficient 
• Find the value of the variable

-4x+1=21

• x=120
• x=5
• x=30
• x=-5

Solve each equation for the following variable. 
1.     x - 4 = 12

• x = 8
• x = 16
• x = -8
• x = 3

10.    x / 2  - 5 = 3

• x = -2
• x = 2
• x = 16
• x = 8

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
