Question

2x-2y=2,4x-y=4 solve by elimination method​

Answer 1

Step-by-step explanation:

(2x+2y=2) ×2 = 4x+ 4y= 4. --------- 1 eq

4x - y= 4 ------------- 2 eq.

subtracting equation 2 from 1

4x-4y=4

4x-y=4

------------

5y = 0

y=0/5

y= 0

put the value of y in eq 2

4x-0=4

4x=4

x=4/4

x=1
