(answer on 1 line)

Answer 1

Answer:

6 & 42

Step-by-step explanation:

You can solve this with two variables and two equations. Note: a = first number; b = second number.

a + b = 48

b = 7a

The easiest way to solve this system of equations is to plug in 7a for b.

1. a + 7a = 48
2. 8a = 48
3. a = 6

Then, plug in a for the first equation to get b.

1. 6 + b = 48
2. b = 42
