Hey there! 

If z = 5 

we replace "z" with "5" 

So, let's test out the problem to see if it is true or false

Problem becomes: 3(5) = 2(5) + 5

Let's work this out

3(5) = 15

Problem becomes: 15 = 2(5) + 5

2(5) = 10

Problem becomes: 15 = 10 + 5

10 + 5 = 15

So, therefore it looks like this statement/ sentence is True!

One number exceeds another by 20 . The sum of the numbers is 78. What are the numbers
castortr0y [4]

Answer: 2 numbers are 19 and 39

Step-by-step explanation:

<em>y = x + 20</em>

Equation: x + y  + 20 = 78

⇔ x + y = 78 - 20

⇔ x + y = 58

⇔ y = 58 - x

So, we have:

x + 20 = 58 - x ( = y)

⇔ x + x = 58 - 20

⇔ 2x = 38

⇔ x = 19

⇒ y = x + 20 = 19 + 20 = 39
