Answer:

x = 1.74

Step-by-step explanation:

It is required to find the value of x in the following equation :

[tex]15(2x-10)+4x=-3(15x+4)[/tex]

Firstly, it is required to solve brackets such that,

[tex]30x-150+4x=-45x-12[/tex]

Collecting variable on one side and constants on another side.

[tex]30x+4x+45x=150-12[/tex]      

[tex]79x=138[/tex]

Dividing both sides by 79 such that,

[tex]x=\dfrac{138}{79}\\\\x=1.74[/tex]

So, the value of x = 1.74.
