it like 7-4 but then you change the sign to negative since you chance it earlier.
3x+ 54=180
straight angle is 180
So just solve the equation.
subtract 54 on both sides.
126=3x
divide that by 3, and you get 42.
check You answer by multiplying 42 And 3, Which basically Is 126
and then 126+54
which is then 180
