Question

2x+3=17 and x =7

It’s for algebra class please help my teacher is really strict but okay please thank u a lot

Answer 1

The equation is true/ or an identity

Explanation:

Plug in 7 for x, you get

2(7)+3=17

14+3=17

17=17

Answer 2

14+3=17

or

(2*7) +3=17

basically 17=17

Explanation:

2x+3=17 and x =7

Let's Substitute:

(Because the variable is x and we have a value for it which is 7)

(Bold and underlined is where the variable is in the equation)

Since x is equal to 7 we are going to substitute it in the equation.

So:

1. (2*7) +3=17

14+3=17

I think this is the answer since already having the value of x is an answer please let me know if I am wrong or answered incorrectly so I can change my answer or let everyone know its wrong so it can be deleted. I only want to spread truthful information and assistance so let me know how I did by rating the answer, saying thanks or reporting it so I can improve.
