Linear equation practice

Practice session

What you practise

Every question asks for x. Watch the signs when you move a term to the other side: that is the slip the feedback looks for first. For the graph behind these equations, open the linear function simulation.

Example

Calculate x in 2x + 3 = 11.

1. 2x = 11 − 3 = 8
2. x = 8 ÷ 2 = 4

Answer: 4.

What you need to know

Linear equations in the 2027 central exam syllabus (wiskunde B), for the levels with a source. A checklist, not the full exam list.

• Solving ax + b = c
• Moving terms with the right sign
• Dividing both sides by the coefficient

• x on both sides: ax + b = cx + d
• The balance method without sign errors

We have not checked the vmbo syllabus for linear equations yet; practice works at every level.

Formula sheet

• Form $$ax+b=c$$
• Solution (a ≠ 0) $$x=\frac{c-b}{a}$$
• Example 2x + 3 = 11 → x = 4 $$x=\frac{11-3}{2}=4$$

Equation (vergelijking)

A math sentence with = in which you look for an unknown, usually x.

Balance method (balansmethode)

Doing the same thing to both sides of the = so the equation stays balanced.

Practice with real exam questions on Examenblad.nl (in Dutch). We do not host past exams.

Frequently asked questions

What if a = 0?

Then there is no x left to solve for in ax + b = c. The solver rejects a = 0 for that reason.

Which calculator goes with this?

The linear equation solver shows the same steps.
