2x + 2 > 10 

Subtract 2 on both sides 

2x + 2 - 2 > 10 - 2

2x > 8

Divide 2 on both sides 

2x/2 > 8/2

x > 4

Hope this helped ;P

Oh I see Phill explained it better than I did use Phills. The inequality symbol was this ( ≤ ) symbol not <= ok I understand.

54-10x<=20+7x

Subtract 54 on both sides 

54 - 54 -10x <=20 + 7x - 54

-10x=7x - 34

Subtract 7x on both sides

-10x - 7x = 7x - 34 - 7x

-17x = -34

Then divide -17 on both sides

-17x/-17 = -17/-34

Dividing two negatives makes a positive

x = 2

The inequality symbol was not useful so it was left behind, it had no corolation with the equation. 

Hope this helped ;P

-15.6 ÷ -4

If you divide two negative together it creates a positive so you would know that it creates a positive

The pen costs $1.05 and the pencil costs $0.05

Hope this helped ;P

Thanks CPhill ;P

Night ;)

Hi ;P

3/4g=-12

Multiply both sides by 4

4*3/4g = 4(-12)

3g = -48

Then divide both sides by 3

3g/3 = -48/3

g = -16

Hope this helps ;P
