Question

Solve the equation:

p-1 by 2 +2p+5 by 3=7​

Answer 1

Answer:

$\frac{p - 1}{2} + \frac{2p + 5}{3} = 7 \\ \\ = > \frac{3(p - 1) + 2(2p + 5)}{6} = 7 \\ \\ = > \frac{3p - 3 + 4p + 10}{6} = 7 \\ \\ = > \frac{7p + 7}{6} = 7 \\ \\ = > 7p + 7 = 42 \\ \\ = > 7p = 42 - 7 \\ \\ = > 7p = 35 \\ \\ = > p = \frac{35}{7} \\ \\ = > p = 5$
