Question

2. Ifx - 2 = 5, what is the value of |2x - 52 23

Answer 1

Solve the equation (x/3)-2=1/3 implies,

$\begin{gathered} \frac{x}{3}=\frac{1}{3}+2 \\ \frac{x}{3}=\frac{7}{3} \\ x=7 \end{gathered}$

Put 7 for x in the equation |2x-25| gives,

$\begin{gathered} |2x-25|=|(2\times7)-25| \\ =|14-25| \\ =11 \end{gathered}$

Thus, the answer is 11.
