one thing that may help is the use of diagrams. See the attached photo.

To solve you need two equations.

2w + 2L = 22
L = w + 3

2w + 2(w + 3) = 22
2w + 2w + 6 = 22
4w + 6 = 22
4w = 16
w = 4

L = w + 3
L = 4 + 3
L = 7

What is a good way to ace a level 5-7 maths test? I need some good tactics...subjects in particular.
zavuch27 [327]
It's important to study and study. I recommend studying the homework or study sheet the day before the test. Most likely the teacher has added a similar problem on to the test. Add a friend to help you study. To make it fun, buy candy and quiz yourself or friends! If you get a problem right, them give yourself candy.
