Solye for x
7(x + 1) = 21

x = 2

Step-by-step explanation:

Given

7(x + 1) = 21 ( divide both sides by 7 )

x + 1 = 3 ( subtract 1 from both sides )

x = 2

x=2

Step-by-step explanation:

7×(x +1)=21

7x +7 =21

7x =21 - 7

7x =14

x=14 :7

x=2

7 ×(2 +1)=21

7 ×3 =21

21 =21

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
