Solve Math Equation Solutions

Introduction to solve math equation solutions:
An equation is a mathematical statement that asserts the equality of two expressions. Equations consist of the expressions that to be equal on opposite sides of an equal sign. (Source: From Wikipedia).

The following rules are used to solve the equation and the equation does not change: Add or subtract any variable or number to the both sides of the equation. Multiply or divide any variable or number to the both sides of the equation. I like to share this Solving Equations Using Addition and Subtraction with you all through my article.

Now, we are going to see some of the problems on how to solve math equations solutions.

Problems to Solve Math Equations Solutions:
Example problem 1:

How to solve an equation for the variable a: a + 23 = 26

Solution:

a + 23 = 26

Subtract 23 on both sides of the equation

a + 23 – 23 = 26 – 23

a = 3

So, the answer is a = 3.

Example problem 2:

How to solve an equation for the variable t:` t / 8 ` = 10

Solution:

`t / 8` = 10

Multiply 8 on both sides of the equation

`(t / 8)` * 8 = 10 * 8

t = 80

So, the answer is t = 80. Is this topic Mathematical Induction hard for you? Watch out for my coming posts.

Example problem 3:

How to solve an equation for the variable m:  5m - 7 = -8

Solution:

5m – 7 = -8

Add 7 on both sides of the equation

5m – 7 + 7 = -8 + 7

5m = -1

Divide by 5 on both sides of the equation

`(5m) / 5 = -1 / 5`

m =` -1 / 5`

So, the answer is m = `-1 / 5` .

Example problem 4:

How to do solve an equation for the variable c:  -2c - 86 = -136

Solution:

-2c - 86 = -136

Add 86 on both sides of the equation

-2c - 86 + 86 = -136 + 86

-2c = -50

Divide by -2 on both sides of the equation

`(-2c) / -2 = (-50) / -2`

c = 25

So, the answer is c = 25.
