Mark me brainliest

and flw

Step-by-step explanation:

An equation is a mathematical expression that contains an equals symbol.

Equations often contain algebra. Algebra is used in maths when you do not know the exact number in a calculation.

an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

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.

Here is an example of an equation:

y + 5 = 10

According to 2x=9

x = 9/2

x = 4.5

verify

By putting x value in equation

2(4.5)= 9

9=9

All the best

Answer 2

ANSWER-:

YES IT IS A LINEAR EQUATION

REASON:-

• IF AN EQUATION HAVE POWER MORE THAN 1 IS NOT AN EQUATION
• EXPRESSION SHOULD HAVE = SIGN
• THERE SHOULD ONLY BE TWO VARIABLE

Understanding way-:

Given expression

2x=9

• There is only 1 power
• equation is having = sign
• there is only 1 variable

Therefore,it is an equation
