The sum of two numbers is 4. One number is five less than twice the other. Find the two numbers.

Number 1 = 3, Number 2 = 1

Step-by-step explanation:

Create an each for the two number and make the sum of those two numbers equal to 4.

Number 1 we will make x

Number 2 will then be   2x - 5    (five less than two times the first number)

Equation is the sum of the two number and equal to 4

x     +   2x - 5  = 4

3x - 5 = 4

Add 5 to both sides

3x = 9

Divide both sides by 3

x = 3

Test your answer.

Number 1 would be equal to 3

Number 2 would be 2(3) - 5 which is 1

Sum of the two numbers   3 + 1  = 4

the expected value of the random variable : 0, 1 and 2
