Question

8x-5y=11 4x-3y=5 solve using elimination method

Answer 1

8x-5y=11
4x-3y=5
solution;
4(8x-5y=11)
8(4x-3y=5)
it becomes, [32x-20y=44
- [32x-24y=40
(32x-32x)+(20y--24y)=44-40
it becomes 20y+22y=4
44y=4, dividing by 44 on both sides, it becomes y=1/11
thus, y=1/11 but 4x-3y=5
4x=5+3y
4x=5+3/11
4x=55/11+3/11
4x=58/11, cross multiplying, it becomes. 44x=58
x=58/44
x=29/22
therefore, x=29/22 and y=1/11
