Question

The sum of two numbers is 150. The double of the first number and 5 time of the second number are equal to 450. find the numbers.

Answer 1

Answer:

100, 50

Step-by-step explanation:

x + y  = 150

2x + 5y = 450

x = 150-y

2(150-y) + 5y = 450

300-2y + 5y = 450

3y + 300 = 450

3y = 450-300

y = 150/3

y = 50

x = 150-y

x = 150-50

x = 100.
