Equations

Question 4. Five more than three times a number is 26. What is the number?

Question 5. Solve the equation 2(x − 4) = 3x − 11.

What's the unknown?

Question 6. The long side of a rectangle is twice its short side. If the perimeter is 36 cm, how long is the short side?

Lexa Hint · Level 1
Look inside the brackets first. If you multiply both terms inside by 2, what does the left side become?
Is it 2x − 8?
Right. Now what would you do to gather the x terms on one side?
Type your question or your attempt…

It shows the way,
not the answer.

Solexa doesn't put the solution in front of you. First a hint, then guidance, the solution last. What you learn stays yours.

THE TEACHING RULE

A teacher, not a cheating tool

The full solution opens only after you have tried. On online exam pages Solexa turns itself off, a safeguard for schools and parents.

1 · Hint 2 · Guidance 3 · Solution (after 2 tries)
Saying "solve it" doesn't skip a level. Lexa describes the next step and leaves the working to you.
Exam mode: no help on online exam pages

3x + 5 = 26

3x = 31

What's 26 minus 5?
3x = 21 → x = 7
