Concept explainers

Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Answer to Problem 54HP

  13x+  12y  −  9x  −3y  +  45+19z−87z=  4x+9y−68z+45

Explanation of Solution

Given:

Write an expression containing at least 2 unlike terms. Then simplify the expression.

Concept Used:

Algebraic expression containing at least 2 unlike terms: 13x+  12y  −  9x  −3y  +  45+19z−87z

In Algebra, we can add or subtract only the like terms. Like terms are with same variable.

Here are three variables: x , y and z and a constant term 45.

Calculation:

Algebraic expression containing at least 2 unlike terms: 13x+  12y  −  9x  −3y  +  45+19z−87z

Simplify: Arrange the like terms side by side and now add or subtract the like terms.

  13x+  12y  −  9x  −3y  +  45+19z−87z13x−9x+12y−3y+19z−87z+454x+9y−68z+45

Thus, the simplified expression of 13x+  12y  −  9x  −3y  +  45+19z−87z is 4x+9y−68z+45
