Solving Literal/Linear Equations

A-B = C
(solve for A) 

• A = C - B
• A = C + B
• A - C = B
• B = A - C

IR = V
(solve for R) 

• R = IV
• R = I/V
• R = V/I
• R = V - I

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a 

Solve for v

C = xv + x

• (C-x)/x = v

• (C+x)/x = v

• (-C-x)/x = v

• (Cx)/x = v

Solve the following equation.
4x + 3 = -5

• 1/2
• -1/2
• -2
• 2

7(2x - 4) = 42

• x= 5
• x= 8
• x= 2
• x= 9

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

-11 + 3(b + 5) = 7

• 1
• -1
• 3
• -3

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

Solve:
2(2x + 3) = -6(x + 9)

• 1.2
• 6
• -6
• 7.5
