2x -3= -7
solve two step equations using inverses

When you are solving this equation you want to add 3 to both sides because that is the inverse of subtracting 3. The reason you do it to both sides is because you want to balance the equation. After you do this the equation will be -2x=-4. Now you would divide by -2 on both side because x is being multiplied by -2, and the inverse of multiplication is division so:
x = 2.

The answer is x=2 because you would have to +3 to the 3 and the 7 then you have to - from the -2 and the -4 by 2 and then you get x=2
