Question

4(3p+5)-3(2p+7)+9=10​

Answer 1

4(3p+5)-3(2p+7)+9=10

=) 12p +20- 6p -21+9=10

=) 6p +8p =10

=) 14p= 10

=) p = 10/14

=) p = 0.714

Answer 2

$4(3p + 5) - 3(2p + 7) + 9 = 10 \\ 12p + 20 - 6p - 21 + 9 = 10 \\ 12p - 6p + 20 - 21 + 9 = 10 \\ 6p + 8 = 10 \\ 6p = 10 - 8 \\ 6p = 2 \\ p = \frac{2}{6} \\ p = \frac{1}{3} \\ p = 0.33$
