Question

What is the value of 2x when 5x-3=17

Answer 1

`2x = 8`

Explanation:

We first need to find the value of 'x'.

This means that we need to solve for 'x' in the equation that is given.

======================================================

`5x - 3 = 17\\\rule{150}{0.5}\\5x - 3 + 3 = 17 + 3\\\\5x = 20\\\\(5x = 20)/(5)\\\\\boxed{x = 4}`

The value of 'x' is 4.

======================================================

We then need to find the value of '2x' by replacing x with '4' and then evaluating.

`2x; x= 4\\\rule{150}{0.5}\\2 * 4\\\\\boxed{8}`

The value of '2x' is 8.

======================================================

Hope this helps!
