Question

solve the following equation to find the value of x. 4(x + 6) - 11 = 25 a. x = 3 b. x = 9.5 c. x = 7.5 d. x = 6

Explanation:

Step1: Expand the left - hand side

$4(x + 6)-11=4x+24 - 11=4x + 13$
So the equation becomes $4x+13 = 25$.

Step2: Isolate the term with x

Subtract 13 from both sides: $4x+13-13=25 - 13$, which simplifies to $4x=12$.

Step3: Solve for x

Divide both sides by 4: $\frac{4x}{4}=\frac{12}{4}$, so $x = 3$.

Answer:

A. $x = 3$
