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 = IRTfor 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 = xor (y + 6)/5 = x

4. 2x - 3y = 8for 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 + bfor b
    y - mx = b

7. ax + by = cfor y
    by = c - ax
    y = (c - ax)/b...or y = (c/b) - (ax/b)

The correct answer is -4
