Question

whats the way to solve this problem? l4x+1l=6

Answer 1

You have to consider the two versions of the odulus function, the positive and negative.
Firstly try the positive,

4x+1=6
x=5/4

then the negative,

-4x-1=6
4x=-7
x=-7/4

Answer 2

4x+1 = 6 or 4x+1 = -6

Solving the first you get x = 5/4
Solving the second you get x = -7/4

These are your solutions.

Answer 3

14x=6-11
x=-5/14
