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.
