WELL I AM DOING MY ALGEBRA HOMEWORK , AND OUR TASK IS TO EXPLAIN HOW TO DO ALGEBRA .. TELL ME IF I'M RIGHT WITH THE EXPLAINING ..................................................I REALLY WANNA GET GOOD GRADES .... There is an equation 2x - 15 = 3x - 10 Let's try to solve it. Let us add 15 to both sides of the equation. 2x - 15 + 15 = 3x - 10 + 15 -15 and + 15 gives you 0. -10 and +15 gives you 5 Now we can rewrite the equation in more simple and convenient way: 2x + 0= 3x + 5 or 2x = 3x +5 Again let us remove the same weight from the opposite plates of the scale so that balance will not be destroyed. Subtract 3x from the left and the right side of the equation. 2x - 3x = 3x + 5 - 3x. 2x -3x gives -x. 3x - 3x gives 0. Now we can rewrite the equation in more simple way: -x = 5 To find x multiply both sides of equation on -1 (-x ) * (-1) = 5 * (-1 ) x = - 5
