Solve the equation: -6p + 14 and 3p - 2

sleet_krkn [62]

Answer:

p = 16/9

Step-by-step explanation:

$-6p+14=3p-2\qquad\text{subtract 14 from both sides}\\\\-6p=3p-16\qquad\text{subtract 3p from both sides}\\\\-9p=-16\qquad\text{divide both sides by (-9)}\\\\\boxed{p=\dfrac{16}{9}\to p=1\dfrac{7}{9}}$
