Find the coordinates of the point of intersection of the lines y = 5x - 2 and x + 3y = 8.

  1. substitute y=5x-2 into second equation --> x + 3(5x- 2)= 8// 2) factorise and simplify to get 16x=14 3) divide 14 by 16 to calculate the value of x to be 7/8 4) sub value of x into equation 1 to find the value of y to be 19/8 5) write down final answer as (7/8, 19/8)
