Question

To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself. The most important thing to remember is that whatever you do to one side of the equation, you have to do the same thing to the other side. 5 + y = 7

Answer 1

`y = 2`

Explanation:

Given

`5 + y = 7`

Required

Solve

From the analysis attached to the question, we can solve this equation by subtracting 5 from both sides:

`5 + y = 7`

`-5 + 5 + y = 7 - 5`

`0 + y = 2`

`y = 2`
