Question

X/4 + y/5 = 2 and x/2 + y = - 3. Solve for x and y
​

Answer 1

A) x/4 + y/5 = 2

B) x/2 + y = - 3

Explanation:

We multiply A) by -4 and B) by 2

A) -x - 4/5 y = -8

B) x + 2y = -6 then add A) and B)

1.2y = -14

y = 11 (2/3) = -11.6666666...

x + 2y = -6

x = -6 -2*-11.6666666

x = -23.3333332
