A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
combining like terms or subtracting from both sides of the equation.
The variables may have different values.
Simply use the 'Rearranging Formulae' rules, such as adding, multiplying, subtracting, or dividing on both sides to get an integer on one side. For example, this linear equation: 2x + 4 < 9 4 can be subtracted from both sides. = 2x < 5 And now it can be divided by 2 on both sides. = x < 5/2
An example could be: 3x-2 = x-6 and so the variable x = -2
