2x = 3y+6, so
3x = 3/2 (3y+6)
now use that to get
3/2 (3y+6) - 2y = 4
solve for y, and then you can get x.
3x-2y=4
2x-3y=6. using substitution method

Multiply Eq1 by 2 and Eq2 by 3. Subtract Eq2 from Eq1:
6x-4y = 8.
6x-9y = 18.
Diff.:5y = -10
Y = -2.
3x-2y = 4.
3x-2*(-2) = 4.
X =
6x-4y = 8.
6x-9y = 18.
Diff.:5y = -10
Y = -2.
3x-2y = 4.
3x-2*(-2) = 4.
X =
3x + 2y = -5
