Answer:

True

Step-by-step explanation:

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide both sides by 5

x = 3

Plug this number into the next equation and see if it is true

10x + 4 = 34

10(3) + 4 = 34

30 + 4 = 34

34 = 34

This is a true equation, so the the answer is true.

Answer:

True

Step-by-step explanation:

⇒ This is true because the whole equation 10x + 4 = 34 is 2 times more than the other equation 5x + 2 = 17.

⇒ You can see that by multiplying the whole equation 5x + 2 = 17 by 2:

2(5x + 2 = 17)

⇒ To get:

10x + 4 = 34

So both equations are equivalent, which means that the answer is true.

Hope this helps! :)
