How do you solve abs(10+8x)-2>16?
2 Answers
color(blue)(ul(bar(abs(color(black)(x>1, x<-7/2))))
Explanation:
Let's first isolate the absolute value operation:
$\left\mid 10 + 8 x \right\mid - 2 > 16$
$\left\mid 10 + 8 x \right\mid > 18$
When solving absolute value questions, we have to consider the positive and ... |
