First, subtract 6 from both sides to get $|7x| = 4$. Then, solve for $x$ by dividing both sides by 7, which gives $x = \frac{4}{7}$ and $x = -\frac{4}{7}$, since the absolute value of $x$ can be positive or negative.

Solve - ∣7x∣+6=10| 7 x | + 6 = 10∣7x∣+6=10 A) {47,−47}\left\{ \frac { 4 } { 7 } , - \frac { 4 } { 7 } \right\}{74​,−74​}
