Step-by-step explanation:
X+2y=4......1
4x-2y=6
2(2x-y)=6
2x-y=3......2
x=4-2y.......3
put X value in equation 2
2x-y=3
2(4-2y)-y=3
8-4y-y=3
-5y=3-8
y=1
put y value in equation 3
X=4-2y
=4-2×1
X=2
Step-by-step explanation:
The given linear equations to solve are
We will be using the method of ELIMINATION to find the value of x.
Adding equations (i) and (ii), we get
Thus, the required value of x is 2.
