But if you build up a strong basic knowledge of beginner math facts and learn some of the “language” of algebra, you can understand it much more easily.
In most cases, do the addition or subtraction step first.

In Algebra, sometimes you may come across equations of the form Ax B = Cx D where x is the variable of the equation, and A, B, C, D are coefficient values (can be both positive and negative). S (Right Hand Side) gives x = 11 Hence x = 11 is the required solution to the above equation.
In the next section, we present an example of this type of equation and learn how to solve it through simple Algebraic techniques. In the equation Ax B = Cx D, the coefficients A, B, C, D may also be any decimal numbers.Learning Basic Algebra Rules Understanding Variables Learning to Solve Equations by "Canceling" Sharpening Your Algebra Skills Exploring Intermediate Topics Show 2 more...

How much money does she need to buy a game that costs ?Solution: Let x represent the amount of money Jeanne needs.Next we present and try to solve the examples in a more detailed step-by-step approach.Examples given next are similar to those presented above and have been shown in a way that is more understandable for kids.So simple addition and subtraction will not lead to a simplified equation in only one variable.However, we can multiply a whole equation with a coefficient (say we multiply equation (2) with 2) to equate the coefficients of either of the two variables.After multiplication, we get 2x 4y = 30 ------(2)' Next we subtract this equation (2)’ from equation (1) 2x – y = 10 2x 4y = 30 –5y = –20 y = 4 Putting this value of y into equation (1) will give us the correct value of x.2x – y = 10 ------(1) 2x – 4 = 10 2x = 10 4 = 14 x = 14/2 = 7 Hence (x , y) =( 7, 4) gives the complete solution to these two equations.
