Question

What value of x makes the equation true? 15(2x−10)+4x=−3(15x+4)

Answer 1

Answer:

x = 1.74

Step-by-step 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,

$x=\dfrac{138}{79}\\\\x=1.74$

So, the value of x = 1.74.
