Question

(10x-5-18x+6)/15=1/3
find the value of x​

Answer 1

10x- 5-18x+6=5

-8x+1=5

-8x=4

x=1/2

Answer 2

Given,

$\sf{\dfrac{10x-5-18x+6}{15}=\dfrac{1}{3}}$

Multiplying both sides by 3,

$\implies\sf{\dfrac{10x-5-18x+6}{5}=1}$

$\implies\sf{10x-5-18x+6=5}$

$\implies\sf{1-8x=5}$

$\implies\sf{-8x=4}$

$\implies\sf{8x=-4}$

$\implies\sf{x=\dfrac{-4}{8}}$

$\implies\sf{x=\dfrac{-1}{2}}$

Therefore,

${\bold{\sf{x=\dfrac{-1}{2}}}$
