Answer:
x = 1 and y = 1.5
Explanation:
Given that,
12y-6x=12 ..... 1
8y+4x=16 ...... 2
Equation (1) can be written as :
2y-x = 2 ... (3)
Equation (2) can be written as :
2y + x = 4 .... (4)
Adding equation (3) and (4)
2y-x + 2y + x = 2 + 4
4y = 6
y = 1.5
Put y = 1.5 in equation (3).
2(1.5)-x = 2
3-x=2
x =1
Hence, the solution of the above equations are (1,1.5).
