Question

Use the properties of an equality to solve the following equations.

(2) p + 4 = 11

Answer 1

p + 4 = 11
Using the subtraction property of equality, we get:
p + 4 – 4 = 11 – 4
$\Rightarrow$p + 0 = 7

We know:
Any number + 0 = The same number
$\Rightarrow$p = 7

Thus, the value of p is 7.
