Question

x + y = 8 2x - y = 7 solve by elimination method​

Answer 1

x + y = 8

+(2x - y) = 7

__________

3x =15

x = 5

x + y = 8

5 + y = 8

y = 3

Therefore, x = 5 and y = 3

Answer 2

Step-by-step explanation:

x+y=8 equation 1

2x-y=7 equation 2

Subtracting equation 1 from 2

x+y=8

2x-y=7

______

3x=15

x=15/3

x=5

Putting x=5 in equation 1

x+y=8

5+y=8

y+8-5

y=3

The solution of this equation is 5,3.
