@mertsj

Answer 5

1. Multiply the bottom equation by -2
2. Add the result to the first equation.
3. You have now eliminated y.
4. Solve the resulting equation for x.
5. Replace x with the result of step 4 and find y.

Answer 13

We all do. With practice we make fewer.

Answer 14

Merts

Answer 15

okay for finding Y

x-2y=8
(2)-2y=8
-2y=10
y=-5

please tell me that's correct

Answer 16

Use the first equation that says y = -4x+5

Answer 17

So...

Y=-4x+5
Y=-4(2)+5
Y=-8+5
whats next?

Answer 18

Add -8+5

Answer 19

so y=-3
