I hope it has come to your help.
The equation will be 12a – 360 = 216. Then the value of the variable a will be 48.
<h3>What is the solution of the equation?</h3>
The solution of the equation means the value of the unknown or variable.
When you multiply a number by 12 and subtract the product from 360, the difference is 216.
Let the number be a.
Then we have the equation
12a – 360 = 216
By solving the equation, we have
12a = 216 + 360
12a = 576
a = 576/12
a = 48
