Testing Simultaneous Equations

Now would be a good time for you to test what you have learned. Work out the value of each variable in the examples below:

2a + b = 21 a + 2b = 24 5p + q = 100 2p - q = -30 m + n = 0 6m - n = 49

Hints: Rearrange one equation to give you one variable. Substitute it, then solve. Be careful with minus signs!
