Given the numerical equation:
5a -10(3) =45
Solve for a.
Solution:
Multiply first the value inside the parenthesis, and transpose the product on the other side of the equation. Note that when a number is transpose, the sign changes.
5a -30 = 45
5a = 45+30
5a = 75
Divide both sides by 5 in order to get the value of a.
5a/5 = 75/5
a = 25
