Question

solve the following pair of linear equations graphically 2x-y=2 and x-y=7

Guys please help me ​

Answer 1

Answer:

x=3  y=-4

Step-by-step explanation:

2x-y=2      +         x-y=7

2x+x=7+2

3x=9

x=3

y=-4

Answer 2

Answer:

x=-5

y=-12

Step-by-step explanation:

2x-y=2 ----->1

x-y=7 ------->2

consider both equation as 1 and 2 and subtract the y from both and get as X=-5 substitute that in equation number 2 then we get y as -12

for verification put x=-5 and y =-12 in equation number 2

7=7 both are same so we got correct answer
