Explicación paso a paso:
1.) P(x;y)
1.) P(x;y) 2x = -7 + 5
2x = -7 + 5 x= -1
2x = -7 + 5 x= -1 2y = 4 - 2
y = 1
P ( -1 ; 1)
2.) M(x;y)
2x = 14 - 6
x=4
2y = -5 + 1
y = -2
M( 4 ; -2)
3.) 2a + 2 = 9 - 3
2a = 4
a = 2
2b - 4 = 7 - 1
2b = 10
b = 5
piden : a + b => 7
4.) 10 = 9 + a
1 = a
8 = 6 + b
2 = b
piden : a + b => 3
