When you've entered an equation, you get this:Īnd if I want to have another equation being solved? You divide by the number in front of the variable and the equation is solved. Subtract a number cleverly on both sides Finally, there should be a multiple of the variables on one sode and a number on the other side. Then, simplify with equivalence transformations. In the exact same manner you can always proceed: First, simplify both sides of the equation as far as possible. The equation is solved now is a solution of it. Now, we divide both sides by the number in front of the x: Now, we have to get the number on the other side. Since we don't like the x on the right side, we substract x on both sides. Next, you have to rearrange the equation in such a way that x is on the left side and numbers on the right side.
