How to solve a-2+3=-2

-3-2+3=-2

The answer to A=-3

So you add like terms

so if you take the - 2+3 part, we know that - 2+3=3-2 = 1 so we can put 1 in place of - 2+3 so

a+1=-2

now we can do anything to the equation as long as we do it to both sides except divide by zero so

subtract 1 from both sides

a+1-1=-2-1

remember that - 2-1 = (-2) + (-1) = - 3

a+0=-3

a=-3
