Level 1 Level 2 Level 3 Level 4 Level 5 Level 6 Description Help More

This is level 1; Equations that can be added or subtracted to eliminate one variable. You can earn a trophy if you get at least 9 correct. Show all of your working in your exercise book.

3x + y = 28
2x + y = 20

x= y= Correct Wrong

x + 3y = 19
2x + 3y = 23

x= y= Correct Wrong

4a + 3b = 42
a + 3b = 24

a= b= Correct Wrong

2c + d = 10
2c + 3d = 22

c= d= Correct Wrong

2ef = 6
-2e − 4f = -46

e= f= Correct Wrong

-2g + 4h = 20
-2g − 4h = -36

g= h= Correct Wrong

5j − 4k = -34
5jk = -16

j= k= Correct Wrong

8m − 4n = 40
8m + n = 10

m= n= Correct Wrong

-9p − 6q = 45
-8p + 6q = 108

p= q= Correct Wrong

-5r + 7s = -53
-5r − 7s = 3

r= s= Correct Wrong

-12u + 4v = 68
8u − 4v = -48

u= v= Correct Wrong

-12w − 5z = 105
11w − 5z = -10

w= z= Correct Wrong

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those.
