The two equations can be solve using substitution method. <span>-3x + y = -11 .....................(1) 2X + 5y = 30 .....................(2) </span> From equation 1, -3x + y = -11 y=-11+3x y=3x-11
Substitute the vale of y in equation 2 with y=3x-11, 2X + 5y = 30 2x + 5(3x-11) = 30 2x + 15x - 55 = 30 17x -55 = 30 17x = 30+55 17x = 85 x =85/17 = 5
