Question

7x +3/2 -(x-3)/4 =20
​

Answer 1

Step-by-step explanation:

7x+3/2-(x-3)/4=20

28x+6-(x-3)/4=20

28x+6-x+3=80

27x+9=80

27x=71

x=71/27

Answer 2

$\huge \bold \color{green}{ \underline { \underline \red{required \: answer : }}}$

$\bold{7x + \frac{3}{2} - \frac{(x - 3)}{4} = 20} \\ \bold{ \implies \: \frac{28x + 6 - x + 3}{4} = 20} \\ \implies \: \frac{27x + 9}{4} = 20 \\ \implies \: 27x + 9 = 80 \\ \implies \: 27x = 80 - 9 \\ \implies \: 27x = 71 \\ \implies \: x = \frac{71}{27}$

so value of x is 71/27
