If 7 + 3x = 22, thеn 2х =?
ООООО

2x = 10

Step-by-step explanation:

First you need to solve for x

7 + 3x = 22

3x = 15

x = 5

Now that we know x we can calculate 2x

2x = 2 * 5 = 10

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
