Question

what is the value of x x/2 + x/3 = 180°​

Answer 1

2x +x+90=180

take 90 to the other side and its sign changes

therefore we have 2x+x=180–90

2x and x are same constants and can be added together therefore we have 3x=90

now take the 3 to the other side and it divides 90, so we have x=90/3 which is x=30

hence x is 30, we can further verify this by placing the value of x in given equation

ie 2(30)+(30)+90 = 60+30+90 = 90+90 = 180

therefore x=30 is correct
