6 - 3(2x - 4) = 2(1 + x)
6 - 6x + 12 = 2 + 2x
18 - 6x = 2 + 2x
18 = 2 + 8x
16 = 8x

     6 - 3(2x - 4) = 2(1 + x)
6 - 3(2x) + 3(4) = 2(1) + 2(x)
     6 - 6x + 12 = 2 + 2x
     6 + 12 - 6x = 2 + 2x
           18 - 6x = 2 + 2x
            <u>   + 6x       + 6x</u>
                  18 = 2 + 8x
                 <u>- 2  - 2         </u>
                  <u>16</u> = <u>8x</u>
                   8      8

<h2><em><u>Option</u></em><em><u> </u></em><em><u>B</u></em><em><u>:</u></em></h2><h3><em><u>112</u></em><em><u> </u></em><em><u>families</u></em><em><u> </u></em></h3>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

No. of families = 75

Out of 75 no. of families had cars = 42

<em><u>Therefore</u></em><em><u>, </u></em>

Out of 200 families, no. of families had cars

= 200 \times  \frac{42}{75}

=200 \times   \frac{14}{25}

= 8 × 14

= 112

<em><u>Hence</u></em><em><u>, </u></em>
