$p = 2 \times (( - 3x - 5) + (3 - 4x)) \\$

Collect like terms

$p = 2 \times ( - 7x - 2)$

p = - 14x - 4

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

p = 66

Thus ;

- 14x - 4 = 66

Add sides 4

- 14x - 4 + 4 = 66 + 4

- 14x = 70

Divide sides by -14

$\frac{ - 14x}{ - 14} = \frac{70}{ - 14} \\$

$x = - \frac{7 \times 10}{7 \times 2} \\$

$x = - \frac{5 \times 2}{2} \\$

x = - 5

Done...
