Question

Solve for x : 2x-(7-5x)/9x-(3+4x) =7/6B

Answer 1

Answer:

x = 3

Step-by-step explanation:

Given :

$\displaystyle{\dfrac{2 x - ( 7 - 5 x ) }{9x-(3+4x)}=\dfrac{7}{6}}\\\\\\\displaystyle{\dfrac{2 x - 7 +5 x}{9x-3-4x}=\dfrac{7}{6}}\\\\\\\displaystyle{\dfrac{7x - 7}{5x-3}=\dfrac{7}{6}}\\\\\\\displaystyle{6(7x-7)=7(5x-3)}\\\\\displaystyle{42x-42=35x-21}\\\\\displaystyle{42x-35x=42-21}\\\\\displaystyle{7x=21}\\\\\displaystyle{x=21/7}\\\\\displaystyle{x=3}$

What is did there :

Just open the bracket with changed the sign.

Crossed multiplied and transferred the same term and find value.

Finally we got x = 3.
