Question

What would you use to solve the equation 12.7 = j-3.4

Answer 1

By the Addition Principle of Equality, I would add 3.4 to both sides of the equation to get rid of the constant term -3.4 on the right-hand side.

12.7 + 3.4 = j - 3.4 + 3.4
16.1 = j

So, j is equal to 16.1.

Answer 2

12.7 = j - 3.4

We're simply just trying to get j by itself.

So, add 3.4 to both sides.

12.7 + 3.4 = j

Simplify.

16.1 = j

So, j = 15.1
