2nd Year Algebra

Simplify the following;

3x + 4 + 2x -3

• x + 1

• 5x + 7

• 5x + 1

• 2x -1

Simplify:

x - 3 -6x -4

• 5x -7

• -5x -7

• 4x + 3

• 6x - 7

Expand;

(3)(x+4)

• 4x + 3

• 3x -6

• 3x + 12

• 4x + 30

Expand:

(4)(2x-2)

• 4x - 8

• -8x - 4

• 8x - 8

• +9x - 3

Expand:

(2x)(3x + 1)

• 3x² + 2x

• 4x - 1

• 5x² + 2x

• 6x² + 2x

(3x)(x + 5)

• 4x² + 15x

• 3x² + 15x

• 4x + 15

• 15x² + 3x

Expand the following:

(9x)(2x + 3)

• 11x + 27

• 18x + 3

• 18x² + 27x

• 11x + 12x²

Solve for x;

4x - 3 = 3x + 9

• x = 6

• x = 12

• x = 2

• x = 13

-3x - 3 = 6x + 6

• x = 1

• x = 2

• x = -1

• x = -3

Solve for x:

9x = 3x + 6

• x = 3

• x = 4

• x = 1

• x = 2
