Example 1 - Collect like terms/simplify:Edit

a) 3x + 2 (1-x)
= x + 2


b) 3(2y - 1) - (4y + 3)
= 6y - 3 - 4y - 3
= 2y -6


Example 2 - Solve:Edit

a) x - 5 = 4
x = 9


b)$ \frac{n}{3}+1=7 $

n + 3 = 21

n = 18


c) $ \frac{3t + 1}{2} = \frac{1}{3} (2t + 6) $

$ 3(3t + 1) = 2(2t + 6) $

$ 9t + 3 = 4t + 12 $

$ 5t + 3 = 12 $

$ 5t = 9 $

$ t = \frac{9}{5} $


d) $ \frac{x}{4} + \frac{1}{3} = \frac{-1}{6} $

3x + 4 = -2

x = -2
