In the equation q - 12 = 89, what is the value of q?

Solution:

A linear equation can be written in different ways.

Any simple equation in x and y can be termed as a linear equation if it follows a certain set of rules.

For example, the highest (and the only) degree of both - x and y - variables in the equation should be 1.

Other than that, constants (zero degree variables) can be there.

Given equation is:

q - 12 = 89

Now, to keep only the variable q to left hand side of the equation, add 12 on both the sides of the equation,

⇒ q - 12 + 12 = 89 + 12

⇒ q = 89 + 12

⇒ q = 101

In the equation q - 12 = 89, what is the value of q?

Summary:

In the equation q - 12 = 89 , the value of q = 101
