The sum of two numbers is 48.

The second number is seven times the first number.

Work out the two numbers.

(answer on 1 line)

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.

a + 7a = 48 8a = 48 a = 6

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

6 + b = 48 b = 42
