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} (x)/(3)=(1)/(3)+2 \\ (x)/(3)=(7)/(3) \\ x=7 \end{gathered}`

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

`\begin{gathered} |2x-25|=|(2*7)-25| \\ =|14-25| \\ =11 \end{gathered}`

Thus, the answer is 11.
