First of all, you have to know what you're looking for ... a number that you can
put in place of 'x' and make the whole statement true. There's only one number
that will work.
-4 + 7 = 5x - 2
Combine the numbers on the left side:
3 = 5x - 2
Add 2 to each side of the equation:
5 = 5x
Divide each side by 5:
1 = x
