Question

**MEDAL**
Solve.
-7x-3y=-25
-6x-4y=-20

Answer 1

\[-6(7x)-3y=-25 and -7(-6x)4y=-20\]

Answer 2

you - the two equation so you wil just have y.

Answer 3

Okay, so is −6(7x)−3y=−25and−7(−6x)4y=−20 the answer? This was the last step up a question I didn't understand :l I got the beginning though!

Answer 4

Yes.

Answer 5

Thanks, guys :P

Answer 6

no haha:) its like (-42x -3y= -25) + (42 x -4y=20) each term is together so -7y=-5

Answer 7

Oh, i see now!

Answer 8

so you can find your y and after, you put this y in one of the two equations and you find the x :)

Answer 9

Thanks! :D
