Concept of Cross Multiplication Method?

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬​

Answer 1

Answer:

the method of cross-multiplying means that we multiply the numerator of each (or one) side by the denominator of the other side, effectively crossing the terms over: The mathematical justification for the method is from the following longer mathematical procedure.

Answer 2

Pair of linear equation in one variable

The linear equations in one variable is an equation which is expressed in the form of

ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x = 5/2.
