Twice a number plus three times a second number is negative one. The first number plus four times the second number is two.

Step-by-step explanation:

The first number is - 2 and the second number is 1

The first number is - 2 and the second number is 1.

Step-by-step explanation:

2n + 3s = - 1

(n + 4s = 2) - 2 Multiply by - 2 to cancel the n

2n + 3s = - 1

-2n - 8s = - 4 Add these equations together

-5s = - 5 Divide both sides by - 5

s = 1

Plug this into the first equation to find the value of n

2n + 3 (1) = - 1 Multiply

2n + 3 = - 1

- 3 - 3 Subtract 3 from both sides

2n = - 4 Divide both sides by 2

n = - 2
