Answer with justification asap....​

Answer 1

Answer:

14

Step-by-step explanation:

Let x be the rows of 25 and y be the rows of 20.

Given, 25x + 20y = 430

5x + 4y = 86 -  ( 1 )

Also x + y = 18 - ( 2 )

Multiply equation ( 1 ) by 4, we get

4x + 4y = 72 - ( 3 )

Subtract equations ( 1 ) and ( 3 ), we get

x = 14
