B) $\left\{ - \frac { 11 } { 8 } , - \frac { 3 } { 8 } \right\}$
C) $\left\{ \frac { 3 } { 8 } \right\}$
D) $\left\{ - \frac { 3 } { 8 } , \frac { 3 } { 8 } \right\}$

Question

Quizplus · Accepted Answer

To solve $| - 8 x + 7 | = 4$, we consider two cases: $ - 8 x + 7 = 4$ and $ - 8 x + 7 = -4$. Solving each equation gives $x = \frac{3}{8}$ and $x = \frac{11}{8}$, respectively.

Solve the Equation ∣−8x+7∣=4| - 8 x + 7 | = 4∣−8x+7∣=4

Solve the Equation $| - 8 x + 7 | = 4$
