Simplifying

Simplify 3(2a + 3b) + 4(2a + 4b)

Simplify 5(3a +2b) - 2(2a + 3b)

b x b x b =

p x q x r =

2a x 3b =

2p x 2q x 2r =

Factorising

1) 2(3a + 4b + 2c)

2) x2(x2 + x + 1)

3) 2y( y2 + 4y + 5)

4) a(b + c + d)

5) 3(x + 4)

Algebra

Solve 2y - 4 = 9

Solve 4( 2x -3) = 5x + 7

Algebra

2y - 4 = 9

2y = 13 

y = 6.5

8x - 12 = 5x + 7
