Log On
|6 - 2x|= 3x + 1
Clear the fraction by multiplying both sides by 2
|6 - 2x| = 6x + 2
There are two cases to consider:
Case 1: When the value of 6 - 2x has the same value as the right side.
6 - 2x = 6x + 2
-8x = -4
x =
Case 2: When the value of 6 - 2x has -1 times the value of the right side.
6 - 2x = -(6x + 2)
6 - 2x = -6x - 2
4x = -8
x = -2
There appear to be two solutions and -2.
However we must check them to see that they satisfy the
original equation.
Checking |6 - 2x|= 3x + 1
|6 - 2()|= 3() + 1
|6 - 1|= 3() + 1
|5| = () + 1
(5) = + =
That checks, so is a solution.
Checking -2
|6 - 2x|= 3x + 1
|6 - 2(-2)|= 3(-2) + 1
|6 + 4|= -6 + 1
|10| = -5
(10) = -5
5 = -5
So -2 is not a solutionh and we discard it.
The only solution is
