Question

Stet by step explanation

Answer 1

x = 4

y = -3

Explanation:

2x + 4y = -4

x + 2y = -2 ---------(1)

3x + 5y = -3 ----------(2)

Equation (1) multiplied by 3 then subtracted from equation (2),

(3x + 5y) - 3(x + 2y) = -3 + 6

-y = 3

y = -3

From equation (1)

x + 2(-3) = -2

x - 6 = -2

x = 6 - 2

x = 4
