Question

The sum of 2 numbers is 49. The second number is 15 less than the first number. The first number is

represented about x and the second number is represented about y. Write the equation that goes with
this description.

Answer 1

x + y = 49

y = x - 15

Explanation:

The sum of 2 numbers is 49 means that x+y = 49. (The two numbers are x and y, and the sum of them are 49.)

The second number is 15 less than the first number, means that y = x - 15 (The second number is y, and it is 15 less than x, which is the first number.)

Therefore the equations will be

x + y = 49

y = x - 15

Answer 2

Explanation:

The sum of 2 numbers is 49

x + y = 49

The second number is 15 less than the first number.

y = x - 15
