Answer:

x = 4.

Step-by-step explanation:

2x + 3(5x - 7) = 47

2x + 15x - 21 = 47

17x - 21 = 47

17x = 68

x = 68/17

x = 4.

Answer:

x = 4

Step-by-step explanation:

   2x + 3(5x - 7) = 47

⇔ 2x + 15x - 21 = 47

⇔ 17x - 21 = 47

⇔ 17x = 47+21

⇔ 17x = 68

⇔ x = 68/17

⇔  x = 68÷17 = 4

This is 7th grade math..........
e-lub [12.9K]

Answer:

A

Step-by-step explanation:

Okay here's my reasoning:

they are telling us that 3 and 5 put together is 8. While this could be either A or D, this question has already told us that it equals 8. This equation is basically more better suited to 8=3+5 because this is show that 8 can be found by putting 3 and 5 together.

Hope this helps!
