● solve linear equations that contain a variable on both sides
So far we have been working with equations that contain a variable on only one side of the equals sign, e.g. 3x + 5 = 32 . However, this is not always the case.
We must also be able to work with equations that contain a variable on both sides.
Worked example 1 Solve the equation: 2x + 6 = x + 11
