You can put this solution on YOUR website! Tell wheather the given value of the varible is a solution of the equation.
-2(3x+7)=-3(2x+8);x=-5.
Let x=-5 and see if both sides equal, if they do, it's a solution, if not, it's not:
-2(3(-5)+7)=-3(2(-5)+8)?
-2(-15+7)=-3(-10+8) ?
-2(-8)=-3(-2) ?
16=6 ????
No, -5 is NOT a solultion!!!
Happy Calculating!!!
