Step-by-step explanation:
Answer:X= 1.84. Y= 3.08
Step-by-step explanation:
-9x+8y =8 ............i
-8x+10y= -16........ii
Multiply equation I by 8
Multiply equation ii by 9
-72x+64y = 64 ..... iii
-72x+90y = 144 ..... iv
Subtract iv from iii
-26y = -80
y= 80/26
y= 3.08
Put the value of y in equation i
-9x+8y =8
-9x+8(3.08) = 8
-9x+24.64 = 8
-9x = 8-24.64
-9x=-16.64
Divide both side by 9
-9x/-9 = -16.64/-9
X= 1.84
