−0.63p − 5.04 + 3.57 = 7.05 + 2.21p?
2 answers:
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:
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
