Answer:
x = 3 and y = 7
Step-by-step explanation:
Given that,
8x+3y=45 .......(1)
2x+3y=27 ........(2)
We need to solve equations (1) and (2)
Multiply equation (2) by 4.
8x+12y=108 .....(3)
Subtract equation (1) from (3).
8x+12y-(8x+3y)=108-45
12y-3y = 63
9y = 63
y = 7
Put the value of y in equation (1).
2x+3(7)=27
2x+21 = 27
2x = 27-21
2x = 6
x = 3
So, the values of x and y are 3 and 7 respectively.
