5x - 7 = 4x - 1...subtract 4x from both sides
5x - 4x - 7 = -1...add 7 to both sides
5x - 4x = -1 + 7...simplify
x = 6

Answer:
w = (S - a) / l
Step-by-step explanation:
Given:
S = a + lw
Find a formula for w in terms of s
S = a + lw
Subtract a from both sides
S - a = a - a + lw
S - a = lw
Divide both sides by l
(S - a) / l = lw / l
(S - a) / l = w
Therefore,
w = (S - a) / l
It can also be written as (S - a ) ÷ l
