Answer 2

Solution :-

$e. \: 3(x + 2) = 15 \\ = > 3x + 6 = 15 \\ = > 3x = 15 - 6 \\ = > 3x = 9 \: \: \: \: \: \: \: \: \: \: \\ = > x = \frac{9}{3} = 3 \: \: \: \:$

$f. \: 5(x + 4) = 25 \\ = > 5x + 20 = 25 \\ = > 5x = 25 - 20 \\ = > x = \frac{5}{5} = 1 \: \: \: \: \:$

$g. \: \: y + \frac{3}{2} = 5 \: \: \: \: \: \: \: \: \: \: \\ = > \frac{2y + 3}{2} = 5 \: \: \: \: \: \: \\ = > 2y + 3 = 5 \times 2 \\ = > 2y = 10 - 3 \: \: \: \: \: \\ = > y = \frac{7}{2} = 3.5 \: \: \: \: \:$

$h. \: \: \frac{3x}{2} + 1 = \frac{11}{2} \: \: \: \: \: \: \\ = > \frac{3x + 2}{2} = \frac{11}{2} \: \: \: \: \: \: \: \\ = > 3x + 2 = \frac{11}{2} \times 2 \\ = > 3x = 11 - 2 \: \: \: \: \: \: \: \: \: \\ = > x = \frac{9}{3} = 3 \: \: \: \: \: \: \: \: \: \: \:$
