Given:-

• 4(3x-3)-2(3x-5)=7

To find:-

• value of x

Solution:-

Now,

$\: \: 4(3x-3)-2(3x-5)=7$

$=>12x-12-6x+10=7$

$=>6x-2=7$

$=>6x=7+2$

$=>6x=9$

$=>x=9/6$

$=>x=3/2$

Verification:-

L.H.S=4(3x-3)-2(3x-5)

$\: \: \: = 4( \frac{9}{2} - 3) - 2( \frac{9}{2} - 5)$

$\: \: \: = 4( \frac{9 - 6}{2} ) - 2( \frac{9 - 10}{2} )$

$\: \: \: = 4 \times \frac{3}{2} - 2 \times \frac{( - 1)}{2}$

$\: \: \: = \frac{12}{2} + \frac{2}{2}$

$\: \: \: = \frac{14}{2}$

$\: \: \: = 7$

$\: \: \: = </u><u>R.H.</u><u>S</u><u>$

Hence proved !!

Answer 2

Answer:

given :-

4(3x-3)-2(3x-5)=7

solution :-

4(3x-3)-2(3x-5)=7

=12x-12-6x+10=7

=6x-2=7

6x=7+2

6x=9

$x = \frac{9}{6}$

$x = \frac{3}{2}$
