Question

I don’t understand this pls help me

Answer 1

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

Answer 2

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
