Please help me solve the following Simultaneous Equation: 4x-7y=-30 5x-7y=-34 Find x and y. needGod.com
5x - 7y = -34................(1) 4x - 7y = -30................(2)
Subtract equation (2) from equation (1) x = - 4. Sub x into equation (1) 5*-4 - 7y = -34 -20 - 7y = -34 -7y =-34 + 20 -7y = - 14 Divide both sides by -7 y = 2 and x = - 4
