What is a simple equation?
In the simplest of terms, a variable and an ‘equal to’ sign make up a simple equation. Therefore, a simple equation is a mathematical representation of two expressions on either side of an ‘equal to’ sign. It mostly consists of a variable, frequently accompanied by a numerical constant.
What is the rule for equations?
Maths – Rules when working of equations
| rule | name |
|---|---|
| x * 1 = x | identity operator – multiplicative (right) |
| 1 * x = x | identity operator – multiplicative (left) |
| if z = x + y then x = z – y | subtracting is the inverse of adding |
| if z = x * y then x = z / y | dividing is the inverse of multiplying |

What is the algebraic equation for a number increased by nine?
Sentence: Algebraic Equation: A number increased by nine is fifteen. y + 9 = 15: Twice a number is eighteen. 2n = 18: Four less than a number is twenty. x – 4 = 20: A number divided by six is eight.
How many times a number is increased by nine?
A number increased by nine is fifteen. y + 9 = 15: Twice a number is eighteen. 2n = 18: Four less than a number is twenty. x – 4 = 20: A number divided by six is eight.
How do you write twice a number in math?
Twice a number is eighteen. Four less than a number is twenty. A number divided by six is eight. Example 2: Write each sentence as an algebraic equation. Twice a number, decreased by twenty-nine, is seven. Thirty-two is twice a number increased by eight.
How do you write algebraic expressions and equations?
To write algebraic expressions and equations, assign a variable to represent the unknown number. In the table below, the letter “x” is used to represent the unknown. In translation problems, the words sum, total, difference, product and quotient imply at least two parts – use parentheses when a sum or difference is multiplied.
