This is a simultaneous equation question. 4x-4y = -40 4x+43 = y Rearrange the second equation so that all the letters and numbers are in line with the first equation remembering to alter the values of the + and - signs. 4x-4y = -40 4x-y = -43 Subtract the second equation from the first equation remembering that a - - is equal to a + This will leave you with -3y = 3 and by dividing both sides by -3 gives you y = -1 Therefore the solution of the simultaneous equation is x = -11 and y = -1. Substitute these values into the original equations to make sure that your solution is correct.
