Substitute values into simple linear equations

Substitute values into simple linear equations

Question 1

Look at this rule.

P = 4T + 2.

The value of P when T = 6 is:

a

8

b

12

c

26

d

48.

Solution (Substitution)

P = 4T + 2.
When T = 6

	P		= 4 × 6 + 2
			= 24 + 2
			= 26.

The answer is c.
