What is an equation?

The equation in mathematics is called algebraic, which means that the two sides of the equation are equal. In that sense, the two sides of the problem are similar. Which is usually there x. X is an unknown number that we must solve by solving it, which one is the desired number. The basic method I use is to put the numbers that have X in one place on the same side and make the numbers one on the other hand, but each number or X is equal to the other when it is equal to it and it is reversed. If it is negative, Positive and, if positive, becomes negative. In the end, the answer at the end of our answer is 3 X = 9; in this case, we will divide 9 into 3 to find the answer for each X, not the three X

The second method is to consider a rectangle for each x and for each square one. To solve this equality, we need to add a number or x on each side, to eliminate each other, to the final stage.

last thing is a we make sure we did that right and everything is ok .we should put our final answer in X and again solving.if the answer is ok ,like 22=22 means every thing is ok!
