Answer:
x = 200
Step-by-step explanation:
Given
 x -
 x -  y = 30 ← substitute y = 15 into the equation
 y = 30 ← substitute y = 15 into the equation
 x -
 x -  × 15 = 30 , that is
 × 15 = 30 , that is
 x - 10 = 30 ( add 10 to both sides )
 x - 10 = 30 ( add 10 to both sides )
 x = 40 ( multiply both sides by 5 to clear the fraction )
 x = 40 ( multiply both sides by 5 to clear the fraction )
x = 200
