Question

Is the equation a true statement when x = 4? In other words, is 4 a solution to theequation?2x + 7 = 3x – 1A. Yes, 4 is a solution to the equation.B. No, 4 is not a solution to the equation.

Answer 1

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

$\begin{gathered} 2x+7=3x-1 \\ Put\text{ x=4 into the equation} \\ 2(4)+7=3(4)-1 \\ 8+7=12-1 \\ 15=11 \\ This\text{ does not give a true statement} \\ \end{gathered}$

Hence, The answer is

No, 4 is not a solution to the equation.
