Linear Equations

How do you solve 9x - 4 = 23

• divide both sides by 4, then add 9

• add 4 to both sides, then divide both sides by 9

• divide both sides by 9, then add 4

• add 4 to both sides, then divide by 23

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

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: 
4x + 1 = 7x - 5

• -1
• 2
• 6/11
• 8

Solve: -7(z - 6) = -70

• 16
