Linear Equations

Linear equations are defined by a function with only one answer. The term "solving" means to leave X alone

For example:

Solve the following linear equation

3(X-4)=5X + 6

Step One:

Take care of the parentheses by distributing the 3

3X -12 = 5X + 6

Step Two:

Group the variables and the numbers together

3X -5X= 12 + 6

Step Three:

Leave X alone:

-2X= 18

X= (-18/2)=-9

X=-9

Final Answer

X= -9
