Question

Solve X and Y (in elimination)
4x = 17 - x-y/8
2y + X = 2 + 5y+2/3
please solve it​

Answer 1

Given equations are, 

4x=17−8x−y

⇒32x=136−x+y

⇒33x−y=136 ....(1)

and 2y+x=2+35y+2

⇒3(2y+x)=6+5y+2

⇒6y+3x=6+5y+2

⇒3x+y=8 ....(2)

Add equations (1) and (2), we get

36x=144

⇒x=4

Put this value in equation (1), we get

33(4)−y=136

⇒132−y=136

⇒y=−4

Therefore, the solution is x=4,y=−4.
