## Online Tutoring Is The Easiest, Most Cost-Effective Way For Students To Get The Help They Need Whenever They Need It.

Equations are the very common and used in almost every topic in mathematics. There are various mathematical operations which are used to simplify and solve equations. Equations consist of one or more than one unknown variables with different coefficients and constant numbers. Exponent is the degree of the variable in the equation. Equations can be solved online depending on the format of learning.

Example 1: Simplify and solve for x in the equation 7 x – 10 = 60?

Solution: Given equation is 7 x – 10 = 60.
Here the unknown variable which needs to be solved for is x.
First step: Adding 10 on both sides of the given equation.
(7 x – 10) + 10 = 60 + 10; This gives 7 x = 70.
Now dividing both sided of the equation by 7.
This gives 7 x/ 7 = 70 / 7.
This reduces the given equation to x = 10.

Hence the solution is x = 10.

Example 2: Simplify the equation 11(x – 1) - 5(x + 1) + 1?

Solution: Given equation is 11 (x – 1) - 6 (x + 1) + 1.
Here the variable is x; distributing the number in front of the braces.
This gives 11 (x - 1) = 11 x – 11; 5 (x + 1) = 5 x + 5.
Combining the similar terms in the equation.
This gives 11 x – 11 - 5 x - 5 + 1 = 6 x -15.

Hence the simplified form of the equation is 6 x - 15.
