Explain how to translate into an algebraic expression four times the difference of eight and a number

4 x (8-x)

Step-by-step explanation:

put eight minus a variable ("a number") in a parentheses to follow PEDMAS and then multiply by 4

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 )
