answer ( 4,3) step by step explaination: solve by using any method u want shush as substitution or elimination but I'm going for elimination so multiply 3 on both sides of the first equation no rewrite it u should now have 9X+6Y=54 now multiply the Bottom equation by 2 you should have 8X-6Y=14 the rewrite again put 9X+6Y=54 on top and 8X-6Y=14 on the bottom -6 and positive 6 is cancelled now 9X+8X is then all u have to do is add 9X+8X and 14 +54 you get 17X=68 then divide X=4 then u have to substitute the X value to the equation 4X-4Y=7 then Y=3
