10|x-3|=40
Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side. Remember to follow the order of operations.
|x-3|=4
Divide both sides by 10.
x-3=4 x-3=-4
Use the definition of absolute value.
x=7 x=-1
Add 3 to both sides of the equation.
