Two numbers have a sum of 24, and 7 times the first number minus the second number is equal to 16. what is the smaller number?

Step-by-step explanation:

Let the first number = x

Let the second number = y

x + y = 24

7x - y = 16                     Add these two equations      

8x = 40                          Divide by 8

8x/8 = 40/8

x = 5

The smaller number will be 5

5 + y = 24

y = 19

Proof

7*5 - 19 = 16

35 - 19 = 16

there are no short passages to look at

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
