2.5x + 5 ≥ 15 I really don't get these

If we are solving for x, then the answer is x = 4

Step-by-step explanation:

move 5 to other side

2.5x + 5 ≥ 15 - 5

2.5x = 10

Get rid of 2.5

2.5x = 10/2.5

x = 4

Hope this helps

Step-by-step explanation:

The equality means that 2.5x+5 is bigger than or equal to 15.

If you want to find x,

2.5x + 5 ≥ 15

2.5x ≥ 10

x ≥ 4

Therefore x is bigger than or equal to 4.

(Remember x may not equal to 4 since it's an equality. So write x ≥ 4, not x =4.)
