Answer:

-6 is the answer.

Step-by-step explanation:

4x - 5 = x - 23

or, 4x - x = -23 + 5

or, 3x = -18

or, x = -18/3

therefore, x = -6

Answer:

the answer is (3)

Step-by-step explanation:

4x - 5 = x - 23

<h3>i) bring -5 to the right-hand side and change its sign</h3>

4x = x - 23 + 5

<h3>ii) calculate the value</h3>

4x = x - 18

<h3>iii) bring x to the left-hand side and change its sign</h3>

4x - x = -18

<h3>iv) calculate the value</h3>

3x = -18

<h3>v) divide both sides of the equation by 3</h3>

$\frac{3x}{3} = \frac{ - 18}{3}$

$x = - 6$
