What properties of equality are these? the options i have are distributive, addition, subtraction, multiplication, division, transitive, symmetric, substitution, and reflexive. 1. x + (3x + 20) = 180 2. 4x + 20 = 180 3. x = 40

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
