Answer:

Step-by-step explanation:

To solve the equation you must isolate the variable.

3x-9=39

So first, add 9 to both sides

3x-9+9=39+9

3x=48

Then divide both sides by 3

3x/3=48/3

x=16

Hi,

The equation looks like this...

$n + 7 \times 2 - 8 \div 2 \\ 3 + 7 \times 2 - 8 \div 2 = 3 + 14 - 4 = 13 \\ 4 + 7 \times 2 - 8 \div 2 = 4 + 14 - 4 = 14 \\ 9 + 7 \times 2 - 8 \div 2 = 9 + 14 - 4 = 19 \\ 12 + 7 \times 2 - 8 \div 2 = 12 + 14 - 4 = 22$

Hope this helps.

(5x 4 – 3x 3 + 6x) – ( 3x 3 + 11x 2 – 8x)

BaLLatris [955]

5x⁴ - 3x³ + 6x) - (3x³ + 11x² - 8x)

Expand the second bracket by multiplying throughout by -1
5x⁴ - 3x³ + 6x - 3x³ - 11x² + 8x

Group like terms and simplify
5x⁴ - 3x³ - 3x³ - 11x² + 6x + 8x

5x⁴ - 6x³ - 11x² + 14x
