3x+2y=7
3x=-2y+7
x=-2/3y+7/3
2(-2/3y+7/3)-3y=-4
-4/3y+14/3-3y=-4
Combine like terms, solve for y, replace y in either original equation to solve for x. Post your work to get it checked.
how do i solve this using the substitution method
3x+2y=7
2x-3y=-4
x=7-2y/3
2(7-2y/3)-3y=-4
this is where i get stuck
help would be much apprieciated
