How to simplify an equation
What does it mean to simplify an equation?
Simplifying an expression is just another way to say solving a math problem. When you simplify an expression, you’re basically trying to write it in the simplest way possible. At the end, there shouldn’t be any more adding, subtracting, multiplying, or dividing left to do. For example, take this expression: 4 + 6 + 5.
How do you simplify an expression example?
Simplifying ExpressionsSolution: a) 14x + 5x = (14 + 5)x = 19x. b) 5y – 13y = (5 –13)y = –8y. c) p – 3p = (1 – 3)p = – 2p. For example, 3x + 2y – 2x + 6. = 3x– 2x + 2y + 6. = (3 – 2)x + 2y + 6. Example: Simplify 3x + 2a – 4x.Solution: 3x + 2a – 4x. =3x– 4x + 2a. = (3 – 4)x + 2a.
How do you simplify numbers?
Some ways to simplify a numberRound it off. Create zeros. So 199 becomes 200.Round to an order of magnitude. Round a lot, to the nearest “power of ten”. Slide the decimal point. Compact those zeros created by rounding. Substitute a number you can remember. Instead of rounding, find a nearby number you can remember.
