Answer:
x = 1
, y = -2
Step-by-step explanation:
2x + 5y + 11 = 0 --- Equation 1
3x - y - 8 = 0
15x - 5y - 40 = 0 --- Equation 2
Equations 1+2: 2x + 5y + 11 + 15x - 5y - 40 = 0 + 0
17x - 29 = 0
17x = 29
x = 29 ÷ 17
x = 1
Substitute x = 1
into Equation 1:
2x + 5y + 11 = 0
2(1
) + 5y + 11 = 0
3
+ 5y = -11
5y = -11 - 3
= -14
y = -14
÷ 5
y = -2
