Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
Answer:
23
Step-by-step explanation:
F = 
express the equation with F on the left side
3F - 24 = s ( add 24 to both sides )
3F = s + 24 ( divide both sides by 3 )
F =
