Open in App

Solution

Check the value satisfies the equation or not:
Let us, substitute the value $a = 15$ in place of the variable and find the value of the Left Hand Side.
$30 - a = 30 - 15 = 15$
Here, Left Hand Side = Right Hand Side
So, $a = 15$ satisfies the equation.
Equation variable Value of the variable Equation satisfied(yes/no)
$30 - a = 15$ $a = 15$ yes

Therefore, $a = 15$ satisfies the equation.
