Question

3-5/7-x/4=1/2+5-4x/8 solve the question

Answer 1

2x + 3 = 7

2x = 7 - 3

2x = 4

x = 2

(ii) 2x - 3 = 7

2x = 7 + 3

2x = 10

x = 5

Answer 2

$\red{\large\mathfrak{Question}}$

⇒\

$⇒ \sf 3 - \frac{5}{7} - \frac{x}{4} = \frac{1}{2} + 5 - \frac{4x}{8}$

$\pink{\large\mathfrak{solution}}$

$\sf \frac{21 - 5}{7} - \frac{x}{4} = \frac{1 + 10}{2} - \frac{4x}{8}$

$⇒\sf\frac{16}{7} - \frac{x}{4} = \frac{11}{2} - \frac{x}{2}$

Transposing the terms :—

$⇒\sf \frac{x}{2} - \frac{x}{4} = \frac{11}{2} - \frac{16}{7}$

$⇒ \sf \frac{2x - x}{4} = \frac{77 - 32}{14}$

$⇒ \sf \frac{x}{4} = \frac{45}{14}$

$⇒ \sf \: x = \frac{45 \times 4}{14}$

$⇒ \sf \: x = \frac{90}{7}$

$⇒ \sf \: x = 12 \frac{6}{7}$
