(1,3) and (-2,-6) are both solutions
Andrews [41]3 years ago

Substitute one by one and see which pair satisfy it.
(-1,3)
3=3(-1)
3=-3 
it is not true,so not a solution.
(2,5)
5=3×1
5=3 
it is not true so not asolution.
(1,3)
3=3×1
3=3
it is true so (1,3)is a solution.
(-2,-6)
-6=3×(-2)
-6=-6
which is true.
Hence (-2,-6) is also a solution.

Which of the following are solutions to | x-1|= 5x + 2 ? Check all that apply.
agasfer [191]

By definition of absolute value, if x-1\ge0, then |x-1|=x-1, so

|x-1|=5x+2\implies x-1=5x+2\implies4x=-3\implies x=-\dfrac34

On the other hand, if x-1, then |x-1|=-(x-1)=1-x, and

|x-1|=5x+2\implies1-x=5x+2\implies6x=-1\implies x=-\dfrac16
