Andrea solves the equation by distributing, isolating the variable, and dividing. The solution is
, which can be confirmed by substituting it back into the original equation.
To solve the equation
for (x), Andrea can follow a systematic process. First, distribute the 4 on the left side of the equation to eliminate the parentheses:
![\[4x + 6 = 7.\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/vlozupwjy98xy07mvnel7ww9zshgcdifpp.png)
Next, isolate the variable term by subtracting 6 from both sides of the equation:
4x = 1.
Now, divide both sides by 4 to find the value of (x):
![\[x = (1)/(4).\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/g30bbryhlrskg279bopa1hk59jfepgqep1.png)
Therefore, the solution to the equation is
. Andrea can verify this solution by substituting
back into the original equation and confirming that both sides are equal.
