Solve the following: 2(5x-3)

Otrada [13]

Answer:

The vale of x is 3/5.

Step-by-step explanation:

First you have to expand out :

$2(5x - 3)$

$= 2(5x) - 2(3)$

$= 10x - 6$

Next you have to solve it by adding 6 to both sides :

Let expression = 0,

$10x - 6 = 0$

$10x - 6 + 6 = 0 + 6$

$10x = 6$

$x = \frac{6}{10}$

$x = \frac{3}{5}$
