A
−25
B
−115
C
−2
D
−559

Answer 1

x = 1.74

Explanation:

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

`15(2x-10)+4x=-3(15x+4)`

Firstly, it is required to solve brackets such that,

`30x-150+4x=-45x-12`

Collecting variable on one side and constants on another side.

`30x+4x+45x=150-12`

`79x=138`

Dividing both sides by 79 such that,

`x=(138)/(79)\\\\x=1.74`

So, the value of x = 1.74.
