To solve the system of linear equations 8x+ by - 18 and 6x+y=-2 by using the linear combination method, Amos decided that he should first multiply the second equation by -5 and then add the two equations together to eliminate the y terms. His calculations are as shown. Amos’s solution is (2,-14). What did he do wrong?
