Question
Solve the equation
x=2
Evaluate
∣6x−30∣=9x
Rewrite the expression
∣6x−30∣−9x=0
Separate the equation into 2 possible cases
6x−30−9x=0,6x−30≥0−(6x−30)−9x=0,6x−30<0
Solve the equation

Evaluate
6x−9x
Collect like terms by calculating the sum or difference of their coefficients
(6−9)x
Subtract the numbers
−3x
−3x−30=0
Move the constant to the right-hand side and change its sign
−3x=0+30
Removing 0 doesn't change the value,so remove it from the expression
−3x=30
Change the signs on both sides of the equation
3x=−30
Divide both sides
33x=3−30
