Question: Solve each literal equation for the indicated variable. 1. P = IRT for T 2. A = 2 (L + W) for W 3. y = 5x - 6 for x 4. 2x - 3y = 8 for y 5. (x + y) 3 = 5 for x 6. y = mx + b for b 7. ax + by = c for y

1. P = IRT ... for T

P / (IR) = T

2. A = 2 (L + W) ... for W

A/2 = L + W

(A/2) - L = W

3. y = 5x - 6 ... for x

y + 6 = 5x

1/5y + 6/5 = x ... or (y + 6) / 5 = x

4. 2x - 3y = 8 ... for y

-3y = - 2x + 8

y = 2/3x - 8/3

5. not exactly sure of the equation here ... (x + y) / 3 = 5? or 3 (x + y) = 5?

6. y = mx + b ... for b

y - mx = b

7. ax + by = c ... for y

by = c - ax

y = (c - ax) / b ... or y = (c/b) - (ax/b)
