Answer 1

Answer:

1.

$\frac{3x - 1}{5} - \frac{x}{7} = 3$

$= > \frac{7(3x - 1) - 5(x)}{35} = 3$

$= > \frac{21x - 7 - 5x}{35} = 3$

$= > \frac{16x - 7}{35} = 3$

$= > 16x - 7 = 3 \times 35$

$= > 16x - 7 = 105$

$= > 16x = 105 + 7$

$= > 16x = 112$

$= > x = \frac{112}{16}$

$= > x = 7$

2.

$2x - 3 = \frac{3}{10} (5x - 12)$

$= > 2x - 3 = \frac{15x - 36}{10}$

$= > 10(2x - 3) = 15x - 36$

$= > 20x - 30 = 15x - 36$

$= > 20x - 15x = 36 + 30$

$= > 5x = 96$

$= > x = \frac{96}{5}$

Answer 2

16)

$\tt \dfrac{3x-1}{5} - \dfrac{x}{7} = 3 \\\\ \tt \Rightarrow \dfrac{7(3x-1)-5x}{35} = 3 \\\\ \tt \Rightarrow \dfrac{21x-7-5x}{35} = 3 \\\\ \tt \Rightarrow 16x - 7 = 3 \times 35 \\\\ \tt \Rightarrow 16x -7 = 105 \\\\ \tt \Rightarrow 16x = 112 \\\\ \tt \Rightarrow x = 7$

17)

$\tt 2x-3 = \dfrac{3}{10}(5x-2) \\\\ \tt \Rightarrow 10(2x - 3) = 3(5x-12) \\\\ \tt \Rightarrow 20x - 30 = 15x - 36 \\\\ \tt \Rightarrow 5x = -6 \\\\ \tt \Rightarrow x = \dfrac{-6}{5}$
