This is the problem: 5 = 51 - a
Help :idea:
Thanks, Linda
All you really need to know in solving these problems is to do exactly the same thing on one side of the = as you do on the other. And you want letters on one side and numbers on the other.
So, 5=51-a Subtract 51 from each side
5-51=51-51-a Do the subtraction
-46=-a You want the letter to be positive so multiply
by -1
-1(-46)=-1(-a) Two negatives multiplied become positive
46=a
