Answer:
x = 3 and y = 1
Explanation:
Give system of equations are :
8x-9y=15 ...(1)
−x+4y=1 ...(2)
Multiply equation (2) by 8.
−8x+32y=8 ..(3)
Add equation (1) and (3).
8x-9y -8x + 32y = 15+8
23y = 23
y = 1
Put the value of y in equation (2).
−x+4(1)=1
-x = -4+1
x = 3
Hence, the values of x and y are 3 and 1.
