Solution
Given the equation 2x + 7 = 3x – 1
We want to test if x = 4 is a solution.
To do this, we will have to substitute x = 4 into the equation and see if both sides give a true statement
[tex]\begin{gathered} 2x+7=3x-1 \\ Put\text{ x=4 into the equation} \\ 2(4)+7=3(4)-1 \\ 8+7=12-1 \\ 15=11 \\ This\text{ does not give a true statement} \\ \end{gathered}[/tex]Hence, The answer is
No, 4 is not a solution to the equation.
