Question

$5x + 4 \div 7 - 3 - 5x \div 14 = 3 \div 2$
​

Answer 1

Answer:

Use BODMAS rule

Step-by-step explanation:

$5x + 4 \div 7 - 3 - 5x \div 14 = 3 \div 2$

$5x + \frac{4}{7} - 3 - \frac{5x}{14} = \frac{3}{2} \\ = > \frac{5x + 4}{7} - \frac { 42 - 5x}{14} = \frac{3}{2} \\ = > \frac{2(5x + 4) - 42 - 5x}{14} = \frac{3}{2} \\ = > \frac{10x + 8 - 42 - 5x}{14} = \frac{3}{2} \\ = > \frac{5x - 34}{14} = \frac{3}{2}$

Now cross multiply it

$2(5x - 34) = 42 \\ = > 10x - 68 = 42 \\ = > 10x - 68 = 42 \\ = > 10x = 42 + 68 \\ = > 10x = 110 \\ = > x = 11$
