Question

Fill in the missing reason for this

Given: 3x +5=14
Prove:x=3

Statement Reason
3x +5=14 Given
3x=9
X=3

Answer 1

The steps are:

`\begin{array}c\text{step}&\text{reason}\\3x+5=14&\text{given}\\3x=9&\text{subtraction property of equality}\\x=3&\text{division property of equality}\end{array}`

In the first step you subtracted 5 from both sides, in the second step you divided both sides by 3.
