Question

x = 9 - y

2x - y = -3 (elemination)

Answer 1

Substitute one into the other, this is easiest:
\[2(9-y)-y=-3\]
Can you simplify it now and solve for 'y'?

Once you do that, plug this 'y' value back into the first equation, 9 minus something. You'll have 'x' too then.

Answer 2

thnx

Answer 3

np!

Answer 4

x+y=9
2x-y=-3
---------
3x 0 =6
x=6/3 =2
x=2

Answer 5

just because you have wrote there by eliminaton method

Answer 6

so if x=2 and x+y=9 so 2+y=9 so y=7

Answer 7

thank you sir :)
