Question

X - 2y = 4
4x + 3y = 5

Answer 1

1. x = 4 + 2y

2.
`x =(5-3y)/(4)`

Explanation:

1 add 2y to both sides

x = 4 2y + 2y = 4 + 2y

simplify

x = 4 _ 2y

2 subtract 3y from both sides

4x + 3y - 3y = 5 - 3y

simplify

4x = 5 - 3y

Divide both sides by 4

4x/4 = 5/4 - 3y/4

simplify

x = 5-3y/4
