Answer 1

Answer:

15 and 25

Step-by-step explanation:

( x + 10 ) + x = 40

2x. = 40 - 10

x. = 15

hence,

15 and ( 15 + 10 ) = 25

hope you understand

Answer 2

ANSWER:

Assuming Meera's age as X,

We have,

(X + 10) + X = 40

X + X = 2X:

2X = 40 - 10                                                      { Taking 10 on Right Hand Side}

2X =30

X = 30/2 {Taking 2 on right-hand side as 2 and X are in multiplication so sign changes}

X = 15     [ Sania's age]

∵ Sum of Meera and Sania's age= 40

∴ 15 + 10 = 25

So, Meera's age = 25, and Sania's age = 15
