Answer:
Explanation:
S1: 2X+2Y = -4
S2: 3X+8Y = 9
Multiply S1 by 3 and S2 by 2. Resulting S1 and S2 will be
S1: 6X+6Y = -12
S2: 6X+16Y= 18
Subtract S2 from S1
-10 Y = -30
Y= (-30/-10) = 3
Put this Value of Y in either S1 or S2 to get Value of X. I am using S2. You can use S1 as well. Answer will be same
3X+8(3) = 9
3X = 9-24
X=(-15)/3
X=-5
