If 3/2x+2y=x/4-y/2=1, then x-y =​

Answer»

Step-by-step explanation:

\frac{3}{2}x + 2y = 1 =  > 3x + 4y = 2...(1)

\frac{x}{4} -  \frac{y}{2} = 1 =  > x - 2y = 4...(2)

Multiply (2) by 2 and add(1) we GET

3x+4y+2(x-2y)=2+8 =>5x=10 =>x=2. SUBSTITUTE x=>2 in EQUATION (1) =>3(2)+4y=2 =>4y=2-6= -4 =>y= -1. x-y =>2-(-1) =>3. HOPE it helps you.
