Answer:
y=4x-10
Step-by-step explanation:
Answer:
x = -3
y = 8
Step-by-step explanation:
x + 2y = 13 ------------(I)
x = 13 - 2y -----------(II)
-2x - 3y = -18 ----------(III)
Substitute x = 13 - 2y in equation (III)
-2*(13 - 2y) - 3y = -18
-2*13 - 2y *(-2) -3y = -18
-26 + 4y - 3y = -18 {Combine like terms}
-26 + y = -18 {Add 26 to both sides}
y = -18 + 26
y = 8
Substitute y = 8 in equation (II)
x = 13 - 2*8
= 13 - 16
x = -3
x = -3
y = 8
