Question

x + 20% of x = 18 can anyone answer this
PROPERLY.

Answer 1

Answer:

P.S Note that * refers to x (multiplication)

equation = x + 20% of x = 18

               = x + 20/100 * x = 18

               = x + 1/5 * x = 18

               = x + x/5 = 18

               = x * 5 + x/5 * 5 = 18

               = 5x + x = 18

               = 6x = 18

               = x = 18/6

               = x = 3 (answer)
