Question

please make the equation for the question by taking the number as. ( 10y + x )​

Answer 1

Answer:

36

Step-by-step explanation:

let the number be (10y+x)

now: 10y+x = 4(x+y) -------- a

10y + x = 4x + 4y

6y = 3x

x = 2y

again 10y + x = 2xy

10/x + 1/y = 2

for x = 2y

10/2y + 1/y = 2

after simplifying:

4y = 12

y = 3

x = 2y = 2(3) = 6

therefore 10y + x = 30+6 = 36
