Question

Solve The System.
-7x+5y=-34
-3x-2=2

Answer 1

is it -2y?

Answer 2

in the second row?

Answer 3

@brandonloves in the 2nd row is it supposed to be -2y?

Answer 4

yes, sorry

Answer 5

In this case.. I would multiply the first equation by 2... because I want to cancel out the y. Then I would multiply the 2nd equation by 5.

Answer 6

@brandonloves what do you get?

Answer 7

oh ok, lemme check

Answer 8

I got 2 for x, and I also need to find y, so I would multiply them again by -3 and 7 to get rid of the x value?

Answer 9

You would plug in 2.. into either equation.

Answer 10

for x of course

Answer 11

-7(2)+5y=-34

OR

-3(2)-2y=2


solve one

Answer 12

-14+5y=-34

and then move the -14 over, change the sign, divide the 5y and get y=-4

Answer 13

or -6-2y=2 which would also be -4

Answer 14

you rule, thanks!
