Question

One number is 7 more than another. Their sum is 13. What is the number?

Answer 1

Answer:

First number = x + 7 = 10 cm

Second number = x = 3 cm

Step-by-step explanation:

Sum = 13

One number = x + 7

Other number = x

= x + x + 7 = 13

2x + 7 = 13

2x = 6

x = 3

First number = x + 7 = 10 cm

Second number = x = 3 cm

Answer 2

Answer:

10 is the number

Step-by-step explanation:

Let the number be x.

Another number=x-7

x+x-7=13

2x=13+7

x=20/2

x=10

Another number=10-7=3
