You are searching for two integers. The sum of twice the first integer and three times the second integer is nine. At the same t

devlian [24]

Answer: -3 and 5

Step-by-step explanation:

Let x represent the 1st digit and y represent the 2nd digit. Then,

Eq 1: 2x + 3y = 9 → 3(2x + 3y = 9) → 6x + 9y = 27

Eq 2: 3x + 2y = 1 → -2(3x + 2y = 1) → -6x - 4y = -2

5y = 25

y = 5

Substitute y = 5 into either of the original equations to solve for x:

2x + 3y = 9

2x + 3(5) = 9

2x + 15 = 9

2x = -6

x = -3

Check (using the other original equation):

3x + 2y = 1

3(-3) + 2(5) = 1

-9 + 10 = 1

-1 = 1 $\checkmark$
