Question

solve using the addition principle 5=x+4

Answer 1

We know that the Addition Principle states that adding (or subtracting) the same number to both sides of an equation does not change its solution set.

Answer 2

Let's use this here we have
\[5=x+4\]
subtract both sides by 4
\[5-4=x+4-4\]
