To solve would be to rewrite the equation in terms of the variable in the equation. For example, solve: 3x-2=7. You would solve for the variable x; e.g. 3x=9 and x=3.
To evaluate, you would be given an equation with a variable or variables. You would need to be given a value for the variable(s) to substitute into the equation. For example evaluate the equation for x=3; equation is x2+1. Substitute 3 in for x; or 32+1=10.
To simplify, reduce the equation to its simplest form. This will involve operations such as: factoring, adding, subtracting, dividing, canceling terms, and so forth. For example simplify the equation: 3x3/9x2. The 3/9 is simplified to 1/3 and x3/x2 is simplified to x. So the original equation simplified is: 1/3 times x or (1/3)x or x/3.Which is the right answer for most of you who does not know.

Explain how solving inequalities is alike and different from solving equations?
Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").

How do find percent increase and decrease?
How to find percentage? What if you need to calculate percentage increase, but not only by how much a number increased, but also the change in percentage increase between two numbers? The below online calculator will calculate percent increase, and it will also calculate percent decrease, and percent difference calculation as well --> the example will explain how it works.Math Example: How to calculate percentage increase, Decrease or Difference How to calculate percent increase between two numbers? To calculate percent difference, you need to follow these steps:1. Problem: You need to calculate percent % increase from 2 to 102. First Step: find the difference between two numbers, in this case, it's 10 - 2 = 83. Second: Take the difference, 8, and divide by the original number: 8/2 = 44. Lastly, multiply the number above by 100: 4*100 = 400%You're done! You calculated difference of a number in percent, and the answer is a percentage increase of 400%.
