Answer:
Step-by-step explanation:
y = -2x - 10 ----------------------(I)
2x + 5y = 6 __________(II)
Substitute y = -2x - 10 in equation (II)
2x + 5 (-2x -10) = 6
2x + (-2x) *5 + (-10) *5 = 6
2x - 10x - 50 = 6
-8x - 50 = 6
-8x = 6 + 50
-8x = 56
x = 56/-8
x = -7
Plugin x = -7 in equation (I)
y = -2*(-7) - 10
= 14 - 10
y = 4
