Solve Linear Equations in One Variable
-$$9 x - ( 7 x - 1 ) = 2$$
A) $\left\{ \frac { 1 } { 2 } \right\}$
B) $\left\{ \frac { 1 } { 16 } \right\}$
C) $\left\{ - \frac { 1 } { 2 } \right\}$
D) $\left\{ - \frac { 1 } { 16 } \right\}$

Question

Quizplus · Accepted Answer

\begin{align*}
9x - (7x -1) &= 2\
9x - 7x + 1 &= 2\
2x &= 1\
x &= \frac{1}{2}
\end{align*}
Therefore, the solution set is $\left\{\frac{1}{2}ight\}$, which corresponds to choice A.
