What is an algebraic expression in words?

Similarly, when we describe an expression in words that includes a variable, we’re describing an algebraic expression, an expression with a variable. For example, “three more than x” can be written as the algebraic expression. x + 3 x+ 3 x+3 .

How would you write an expression?

To write an expression, we often have to interpret a written phrase. For example, the phrase “6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.

How do you simplify algebraic expressions?

To simplify any algebraic expression, the following are the basic rules and steps:

  1. Remove any grouping symbol such as brackets and parentheses by multiplying factors.
  2. Use the exponent rule to remove grouping if the terms are containing exponents.
  3. Combine the like terms by addition or subtraction.
  4. Combine the constants.

What are the variables in an equation?

Variable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation. Commonly used variables include x and y (real-number unknowns), z (complex-number unknowns), t (time), r (radius), and s (arc length).

What is the formula for solving linear equations?

The standard form of a linear equation in one variable is of the form ax + b = 0. Here, x is a variable, and a and b are constants. While the standard form of a linear equation in two variables is of the form ax + by = c.

How do you solve 6 simultaneous equations?

  1. Add second and third equation to get 2x=180→x=90.
  2. and y=101−90=11.
  3. 11i2+12412=i2+13→i2=120.
  4. b=1320.
  5. And finally a=15150−1320=13830.

What is constant in linear equation?

In a statistical context, a linear equation is written in the form y = a + bx, where aand b are the constants. In the equation y = a + bx, the constant a is called as the y-intercept. Graphically, the y-intercept is the y coordinate of the point where the graph of the line crosses the y axis. At this point x = 0.
