Question

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

(2) x − 10 = 2

Answer 1

When x = 15:
x − 10
$\Rightarrow$15 − 10
= 5

When x = 14:
x − 10
$\Rightarrow$14 − 10
= 4

When x = 12:
x − 10
$\Rightarrow$12 − 10
= 2

Thus, x = 12 satisfies the equation x − 10 = 2.
