Answer:

y=17/3

Step-by-step explanation:

So you should make one -3y positive to cancel them out.

So multiply 2x-3y=43 by -1 and you get

-2x+3y=43

4x-3y=83

now +3y -3y cancel each other out

4x-2x=83-43

2x=50

x=25

Now enter 25 into the equation as x to find y

4(25)-3y=83

100-3y=83

100-83=3y

3y=17

y=17/3
