Answer:

a) x = -9

b) p = (q - x)/3

Step-by-step explanation:

a) Substitute the values in to the equation

x = 3p + q

x = 3(-2) + -3

x = -6 + -3

x = -9

b) Make p the subject

x = 3p + q

(add 3p to both sides)

x + 3p = q

(subtract x on both sides)

3p = q - x

(divide on both sides)

p = (q - x)/3

Answer:

Given

  • x = 3p + q

a)

  • p = -2, q = -3 ⇒
  • x = 3(-2) - 3 = -6 - 3 = -9

b)

  • x = 3p + q
  • 3p = x - q
  • p = (x - q)/3
