Can anyone tell the answer ​

Answer 1

3(y+z)

is the income of three week

hopefully it will help you

Answer 2

Answer:

21y + 3z most probably

Step-by-step explanation:

money spent in one day = y

money spent for 3 weeks = 3×7×y= 21y

money saved in one week= z

money saved for 3 weeks= 3z

total income in 3 weeks = money spent for 3 weeks + money saved for 3 weeks

= 21y + 3z = 3(7y+z)

note:

if you have values for y and z , you may substitute them

I hope this helps :)
