Question

3Ix+5I=7

I= absoulute value symbol

Answer 1

`x = -\frac{8}3~~~~\text{or}~~~x = -\frac {22}3`

Step by step explanation:

`~~~~~3|x+5|=7\\\\\implies |x+5| = \frac 73\\\\\implies x +5=\frac 73~~~\text{or}~~~x+5 = -\frac 73\\\\\implies x = \frac 73 -5~~~\text{or}~~~ x = -\frac 73 - 5\\\\\implies x = -\frac{8}3~~~~~~\text{or}~~~x = -\frac {22}3`
