Review

A solution is any value of [tex]$x$[/tex] that makes an equation true.

Example: We are going to verify if 4 is a solution of the equation [tex]$2x + 3 = 7$[/tex].

To verify if 4 is a solution of the equation, we substitute [tex][tex]$x$[/tex][/tex] by 4.

[tex]\[
\begin{array}{l}
2(4) + 3 = 7 \\
11 \neq 7
\end{array}
\][/tex]

Conclusion: 4 is not a solution of the equation [tex]$2x + 3 = 7$[/tex].



Answer :

Sure, let's review the process of determining if a given value is a solution to an equation.

Step-by-Step Solution:

1. Given Equation: [tex]\(2x + 3 = 7\)[/tex]
2. Proposed Solution: [tex]\(x = 4\)[/tex]

To verify if [tex]\(x = 4\)[/tex] is a solution to the equation, follow these steps:

1. Substitute [tex]\(x\)[/tex] with 4 in the equation:
[tex]\[ 2(4) + 3 \][/tex]

2. Calculate the left side of the equation:
[tex]\[ 2(4) + 3 = 8 + 3 = 11 \][/tex]

3. Analyze both sides of the equation:
- Left side: [tex]\(11\)[/tex]
- Right side: [tex]\(7\)[/tex]

4. Determine if the left side equals the right side:
[tex]\[ 11 \neq 7 \][/tex]

Since the left side [tex]\(11\)[/tex] is not equal to the right side [tex]\(7\)[/tex], the value [tex]\(x = 4\)[/tex] does not satisfy the equation [tex]\(2x + 3 = 7\)[/tex].

Conclusion:
[tex]\[ \boxed{4} \text{ is not a solution of the equation } 2x + 3 = 7. \][/tex]

This step-by-step verification shows that [tex]\(4\)[/tex] does not make the equation true, and thus it is not a solution to the given equation.
