180-x=180-3x
Use the distributive property to multiply 3 by 60-x.
180-x+3x=180
Add 3x to both sides.
180+2x=180
Combine -x and 3x to get 2x.
2x=180-180
Subtract 180 from both sides.
2x=0
Subtract 180 from 180 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 2 is not equal to 0, x must be equal to 0.
