One Step Equations.
One Step Addition.
1) x + 4 = 3
2) x + 7 = -3
3) x + 9 = 14

1) x + 4 = 3

x = 3-4

x = -1

2) x = -3-7

x = -11

3) x = 14-9

x = 5

1) X +4 = 3

X = -1

2) X+7 = -3

X = -10

3) X +9 = 14

X = 5

hope this helps , i am bad at explaining

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.
