Answer:
8=x
Step-by-step explanation:
First of all, substitute -2 for y: -2=-x+6. Then collect like terms by bringing the +6 to the other side to -2 and also change the sign: -6. -2-6=-x. Then solve -2-6 which is -8. Now you are left with -8=-x. Since you want to get x by itself, divide both sides by -1 which will give you x=8
