Question

−0.63p − 5.04 + 3.57 = 7.05 + 2.21p?

Answer 1

Answer:

p = -3

Step-by-step explanation:

-.63p - 5.04 + 3.57 = 7.05 + 2.21p     add  .63p to both sides

-5.04 + 3.57 = 7.05 + 2.21p + .63p

-5.04 + 3.57 = 7.05 + 2.84p add the left side together

-1.47 = 7.05 + 2.84p    subtract 7.05 from each side

-1.47 - 7.05 = 2.84p

-8.52 = 2.84p  Divide each side by 2.84

-8.52/2.84 = p

-3 = p

Answer 2

Answer:

p = -3

Step-by-step explanation:

−0.63p − 5.04 + 3.57 = 7.05 + 2.21p

−0.63p − 1.47 = 7.05 + 2.21p    (add 0.63p to both sides)

− 1.47 = 7.05 + 2.21p + 0.63p

− 1.47 = 7.05 + 2.84p  (subtract 7.05 from both sides)

− 1.47 - 7.05 =  2.84p

-8.52 = 2.84p  (rearrange)

2.84p = -8.52   (divide both sides by 2.84)

p = -8.52 / 2.84

p = -3
