Question

8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .​

Answer 1

The numbers are 13 , 16

Explanation:

First number be x

Second number be y

x - y = -3 --------------------(I)

x = -3 +y

8x + 5y = 184 ---------------(II)

substitute x = -3 + y in equation(I)

8*(-3 + y) + 5y = 184

-24 + 8y + 5y = 184

-24 + 13y = 184

13y = 184 + 24

13y = 208

y = 208/13

y = 16

Plugin y = 16 in (I)

x - 16 = -3

x = -3 +16

x = 13
