Question 1053325: Solve the system of linear equations by substitution. -2x - 5y = 3, 3x + 8y = -6
Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
-2x - 5y = 3 ***
3x + 8y = -6
|
-6x - 15y = 9
6x + 16y = -12
y =
and
Using ****
x = -(5(-3)+3)/2 =
checking
3x + 8y = -6
18 - 24 = -6 CHECKS!
