Solving equations and inequations

Watch this video to learn about working with inequations.

Remember when solving equations and to use the rule:

Change side, change operation

Look at the National 4 solving equations section before continuing.

Example

Solve the equation \(- 2 - 3y = 11\)

Answer

\(- 2 - 3y = 11\)

\(- 3y = 11 + 2\)

Move the -2 over to the right hand side changes it to +2

-3 is multiplying on the left, so when moved to the right it divides

\(- 3y = 13\)

\(y = \frac{{13}}{{ - 3}}\,or\,y = - 4\frac{1}{3}\)

Now try the question below.

Question

Solve the equation \(35 = 5 - 6m\) to find m.
