Question

Solve the system of linear equations by substitution.

Answer 1

(4,5)

Explanation:

`x + 4y = 24\\subtract x from both sides\\4y=24-x\\divide both sides by 4\\y= 6 -- 1/4x\\set equations equal to eachother\\6--1/4x = -x + 9\\subtract 6 from both sides\\-1/4x = -x + 3\\add x to both sides\\\\3/4x = 3\\multiply both sides by 4/3 to get\\x = 4\\\\sub in x into one equation, I picked the first \\\\-4 + 9 = y\\-4 + 9 = 5\\\\\\y = 5, x = 4`
