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 = 26
2x + y = 18

x= y= Correct Wrong

3x + 2y = 25
3x + y = 17

x= y= Correct Wrong

3a + 4b = 40
a + 4b = 32

a= b= Correct Wrong

3c + 2d = 32
3c + 4d = 46

c= d= Correct Wrong

6e − 2f = 22
-2e − 2f = -18

e= f= Correct Wrong

-2g − 7h = -38
g + 7h = 40

g= h= Correct Wrong

-5j + k = 26
5j − 4k = -44

j= k= Correct Wrong

7m + 7n = 21
-7m + n = -69

m= n= Correct Wrong

-7pq = 61
7p + 3q = -71

p= q= Correct Wrong

-2r + 2s = 18
4r − 2s = -22

r= s= Correct Wrong

6u + v = -46
-u + v = 3

u= v= Correct Wrong

-13w − 13z = 0
-13wz = 108

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.
