Maths question. 8x + 3y = 13 / 2x + 2y = 22

first times the second equation by 4 to give you 8x + 8y = 88

then subtract both equations 8x + 3y = 13 - 8x + 8y = 88

gives you 5y = 75 y = 15 then put the value of y (15) into the second equation

2x + 2 x 15 = 22 gives 2x + 30 = 22 2x = 22 - 30 2x = -8 x = -4

answer x = -4 and y = 15
