Question

the sum of three numbers is 6. the third number is the sum of the first and second numbers. the first number is one more than the third number. find the numbers

Answer 1

Answer:

x = 4

y = -1

z = 3

Step-by-step explanation:

Let 1st number = x

Let 2nd number = y

Let 3rd number = z

x+y+z=6

x+y=z

x=z+1

(Apply Simultaneous Equations)

Hence:

z+z=6

2z=6

z=6/2

z=3

Now:

x+y=3

x=3+1

x=4

Now:

4+y=3

y=3-4

y=-1
