Can an equation not have an equal sign?

Notice that expressions do not have equal signs, while equations must have equal signs. An equation is a statement that two expressions have the same value, and the equal sign is a necessity.

What is not an equation?

An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an ‘equals’ sign. For example x=y is an equation where two expressions x and y are equal. Whereas f(x)=x is a function with variable x and hence f(x)=x is not an equation.

Does equations have an equal sign?

An equation is a mathematical sentence that says two expressions are equal. Equations always have an equal sign.

How do you identify an equation?

You can define a numerical expression as a group of numbers and variables with no equal sign. An equation is a group of numbers and variables that does include an equal sign. Once you understand these definitions, you can recognize that an equation is simply two expressions joined together by an equal sign.

What is the example of not equal?

Not equal. Example: 7 and 5 are unequal. The symbol is ≠ (the “not equal” symbol).

What is the meaning of not equal symbol?

inequality
The not equal symbol is a sign of “inequality”. It is meant to show a comparison between the two quantities which are unequal hence, representing inequality among them. It is represented by two parallel horizontal lines cut by an inclined vertical line as (≠ ).

What’s an equation with no solution?

No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable.

What equation has no solution?

If (a1/a2) = (b1/b2) ≠ (c1/c2), then there will be no solution. This type of equation is called an inconsistent pair of linear equations. If we plot the graph, the lines will be parallel.

Which equation is false?

A false equation is an incorrect equation; it says something erroneous or untrue. For example, 2 = 3 is a false equation, because 2 and 3 are different numerical values. To make a true equation, check your math to make sure that the values on each side of the equals sign are the same.

What is a false equation?

A false equation has an =, but the two expressions are not equal to each other. For example, the following is a false equation. 2 + 2 = 6 2+2=6 2+2=6. When we see an equation that’s not true, we can use the not equal sign ( = ) to show that the two expressions are not equal: 2 + 2 ≠ 6 2+2 \neq 6 2+2=6.
