2x-3y=-6x+2y=8 you subtract the 2y from the second equation to get x by itself so you can use the rule of substitution. 2x-3y=-6x=-2y+8now you take what the x is equal to and plug that whole equation into the second equation2(-2y+8)-3y=-6now distribute your parentheses.-4y+16-3y=-6Add your like terms-7y+16=-6Subtract the 16 to one side.-7y=-22Divide by the -7y=22/7Now plug the y value (22/7) into one of the two equations to find the x value.
