Since there is no question I do not know what is being solved for, but if you’re wondering what the value of x and y equal here’s the explanation.
Set up both equations equal to each other > -2x-4 = 3x+3
Subtract 3 from both sides to get > -2x-7 =3x
Subtract the -2x on both sides to get > -7 = 5x.
Divide both sides by 5 and x = -1.40 or (-1 2/5)
In order to get y value take one of the equation and replace the x in the equation with the value of x you just solved for.
y = -2(-1.4) - 4
multiply the number in the parenthesis and the -2 and you get > y = 2.8 - 4
subtract the two and y = 1.2
x = -1.4 (-1 2/5)
y = 1.2 (1 1/5)

Step-by-step explanation:
I hope this helps you, have a nice day! :D
-x+5y=20
5y=x+20
12y=2x+60
6y=x+40
x+20+y=x+40
-x from each side:
20+y=40
-20 from each side:
y=20
-x+5*20=20
-x+100=20
-100 from each side:
-x=-80
x=80
y=20
x=80
Hope this helps :)
