well first collect like terms. so add 2x to -12x and you get 10x. so now the equation is 10x - y = 5. so since it looks like its a graphing problem you need to get it into y = mx + b form and you get -y = -10x + 5. now divide everything by -1 to get rid of the negative sign in front of the y and you y = 10x - 5hope this helped!
