You can put this solution on YOUR website! 1) 3x -3y = -27
:
2) 2x +5y = 10
:
for equation 1, divide both sides of = by 3
:
x -y = -9
:
solve for x
:
x = y -9
:
substitute for x in equation 2
:
2(y-9) +5y = 10
:
2y -18 +5y = 10
:
7y = 28
:
y = 4
x = 4 -9 = -5
:
***********************************************************************
x = -5, y = 4

check the answers
:
equation 1
:
3(-5) -3(4) = -27
-15 -12 = -27
-27 = -27
:
equation 2
:
2(-5) +5(4) = 10
:
-10 +20 = 10
:
10 = 10
:
the answers check
:
here is a graph of equation 1 red line, equation 2 is green line
:
equation 1 in point slope form y = x +9, equation 2 is y = (-2x/5) + 2
