Answer 1

Answer:

Step-by-step explanation:

Ahmed is equal to x

Weiming is equal to y.

y+40 is equal to x.

So (a) y+y+40 is the total

         2y+40 (answer)

(b) Now x is equal to 55 so we substitute that into the above equation

y+40 is equal to 55

55 minus 40 is equal to y

y is equal to 15 (answer)
