Five times one number minus two times a second number is 11. Three times the first number minus two times the second number is 1
damaskus [11]

Answer:

first number is 5

second number is 7

Step-by-step explanation:

let x and y represent the first and second number

5x - 2y = 11 ........ equation 1

3x - 2y = 11.......... equation 2

so by elimination, equation 1 minus equation 2

5x - 3x - 2y - 2y = 11 - 1

2x = 10

x = 5

therefore the first number is 5

put x = 5 into equation 1

5x - 2y = 11

5(5) - 2y = 11

25 - 2y = 11

-2y = 11 - 25

-2y = - 14

y = 7

therefore the second number is 7

hope it helps .

There is a number written on the board. One student increased the number by 23, but another student decreased the same number by
NNADVOKAT [17]

Answer:

5

Step-by-step explanation:

Let's call the original number x.

So, the first student did x+23, and the other student did x-1.

You know that the first students result was 7 times larger than the other students. So, you can make the equation:

x+23=7(x-1)

x+23=7x-7

Then, do the algebra

-6x=-30

x=5
