Solving Linear Equations

Solve: 3(x-4) = -3

• 3
• -3
• 5
• -5

Solve for the variable. 3x=-27

• x=9
• x=-30
• x=-9
• x=-24

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

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

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

Solve:
2(2t - 3) = 6(t + 2)

• t=9
• t=4
• t=-9
• t=-3

Solve for n:
n+2=-14-n

• 6
• 8
• -8

S = 3F - 24  Solve for F

• F = (S + 24)/3
• F = S/3 + 24
• F = 3S + 24
• F = 3(S + 24)

8x + 4y= 16 for y

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

Solve for w:
A = LW

• A = ^L/_W
• w = ^L/_A
• w = A
• w = ^A/_L

3x - 7 = 3(x - 3) + 2
