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

if x decreases by 4 then y increases by 10

step-by-step explanation:

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
