At what point will the lines 3x+6y=-57 and -5x+4y=-45 intersect?

At what point will the lines 3x+6y=-57 and -5x+4y=-45 intersect?
3x + 6y = -57......multiply by 5-5x + 4y = -45....multiply by 3------------------15x + 30y = -285 (result of multiplying by 5)-15x + 12y = - 135 (result of multiplying by 3)-----------------add          42y = - 420             y = -420/42             y = -103x + 6y = -573x + 6(-10) = -573x - 60 = -573x = -57 + 603x = 3x = 3/3x = 1so ur solution (where the lines intersect) is (1,-10) ...
