A number is 14 more than another number. Twice the sum of the two numbers is 8. Find the two numbers

Question

Use a system of linear equations with two variables and two equations to solve.

Answer 1

1st number = x

 

2nd number = x+14

 

2(x + x+14) = 8

 

2(2x+14) =8

2x +14 =4

2x =-10

x =-5

 

1st number = x =-5

2nd number = x+14 =9
