Question

Solve each of the following equation by choosing proper values for the variable in it.

(5) 18 = 13 + y

Answer 1

When y = 2:
13 + y
$\Rightarrow$13 + 2
= 15

When y = 4:
13 + y
$\Rightarrow$13 + 4
= 17

When y = 5:
13 + y
$\Rightarrow$13 + 5
= 18

Thus, y = 5 satisfies the equation 18 = 13 + y.
