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)
