mth 121(solve the linear equation:2x+3y=3, x-2y=5 and 3x+2y=7.)
2x+3y = 3
x-2y = 5
has solution (3,-1)
This point is also on on the third line, so it is the solution to all three equations.
x-2y = 5
has solution (3,-1)
This point is also on on the third line, so it is the solution to all three equations.
