Online Easy Algebra Tutors

Online Easy Algebra Tutors We know algebra is a branch of math in which we can us e the letters to represents the numbers. In this we can use unknown letters; we can call these as variables. In algebra we have expression s and equations. Algebraic expression is a combination of letters or numbers formed according to the rules. Example1: Find the value of x, if x + 10 = 25 2x. Solution: The given equation is x + 10 = 25 2x We can add the number 10 on both sides of the equality x + 10 10 = 25 2x 10 We can write this as x = 15 2x Now we can add + 2x on both sides of the equality x + 2x = 15 2x + 2x we can write this as 3x = 15 Now we can divide this by 3 Then we get x = 5 Example2: Find the value of y, if 19 3y = 4y 9. Solution: The given equation is 19 3y = 4y 9 We can add the number 9 on both sides of the equality 19 3y + 9 = 4y 9 +9 We can write this as 28 3y = 4y Now we can add + 3y on both sides of the equality 28 3y + 3y = 4y + 3y We can write this as 28 = 7y Now we can divide this by 7 Then we get 4 = y So the solution is y = 4
