Question
Solve the equation
x=−452
Alternative Form
x=−0.04˙
Evaluate
30x−12=20x×15
Multiply the terms
30x−12=300x
Move the variable to the left side
30x−12−300x=0
Subtract the terms
More Steps

Evaluate
30x−300x
Collect like terms by calculating the sum or difference of their coefficients
(30−300)x
Subtract the numbers
−270x
−270x−12=0
Move the constant to the right side
−270x=0+12
Removing 0 doesn't change the value,so remove it from the expression
−270x=12
Change the signs on both sides of the equation
270x=−12
Divide both sides
270270x=270−12
Divide the numbers
x=270−12
