To solve this we need to isolate m so we will bring -a/x to the other side of the equal sign so it will become positive i.e. ax now will be written as a/x+Q=m
35 + 52 + 3(x + 2) = 180 87 + 3x + 6 = 180 ( add the like terms and use distributive property) 93 + 3x = 180 -93 -93 3x = 87 ÷3 ÷3 x = 29 ( the sum of all triangle angles is 180)
