Question

One number is 7 more than another number. The sum of the numbers is 63. What are the numbers?

Answer 1

\( \color{Black}{\Rightarrow x + (x + 7) = 63}\)

Solve for x, and x + 7.

Answer 2

x=y+7
x-y=7
x+y=63
add both nd find the answer

Answer 3

Let the other number be : x

So,
First number = x + 7

And given:

x + (x + 7) = 63

2x = 56

Solve for x..

Answer 4

that is 28 and 35

28+35=63

Answer 5

what about my answer?

Answer 6

You've got your answer already...

Answer 7

some number = x
some number +7 = x+7
now combine them to equal to 63 and solve for x.
so we have,
x+(x+7) = 63
x = 28
now since you know the value of one x the other would be 28 + 7 = 35
