Four times a number added to another number is 36. Three times the first number minus the other number is 20. Can you please tell me the numbers?

x = the number

y = other number

4x + y = 36 {four times a number added to another number is 36}

3x - y = 20 {three times the 1st minus other is 20}

-----------

7x = 56 {added the two equations together and eliminated the y}

x = 8 {divided both sides by 7}

The first number is 8

4x + y = 36 {top equation}

4(8) + y = 36 {substituted 8 in for x}

32 + y = 36 {multiplied 4 by 8}

y = 4 {subtracted 32 from both sides}

The other number is 4

8 and 4 are the two numbers
