Answer:

[tex] \huge \boxed{x = - 1}[/tex]

Step-by-step explanation:

[tex] \frac{2x - 10}{4} = 3x \\ [/tex]

Multiply through by 4 to eliminate the fraction

That's

[tex]4 \times \frac{2x - 10}{4} = 4(3x) \\ 2x - 10 = 12x[/tex]

Subtract 12x from both sides of the equation

[tex]2x - 12x - 10 = 0 \\ - 10x - 10 = 0 \\ - 10x = 10[/tex]

Divide both sides by - 10

[tex] \frac{ - 10x}{ - 10} = \frac{10}{ - 10} \\ [/tex]

We have the final answer as

x = - 1

Hope this helps you
