Question

X=4y 0.5+2x=85 eqautions using substititon

Answer 1

x = 42.25; y = 10.5625 = 10.56

Explanation:

First we need to substitute the 4y for x in the second equation, so we get 0.5 + 2(4y) = 85.

Solving for y gives us y = 10.5625.

Plugging y into the first equation gives us x = 4(10.5625), which gives us x = 42.25.
