5x - 3y = 10
x + y = 7......multiply by -5
------------------
5x - 3y = 10
-5x - 5y = -35 (result of multiplying by -5)
------------------add
-8y = -25
y = 25/8

x + y = 7
x + 25/8 = 7
x = 7 - 25/8
x = 56/8 - 25/8
x = 31/8

solution is (31/8 , 25/8)

Answer:

(x + 2, y - 4 )

Step-by-step explanation:

Consider the shift of coordinate point A (- 6, 2 ) → A'(- 4, - 2 )

This represents a shift of + 2 units in the x- direction and

a shift of - 4 units in the y- direction, thus

(x, y ) → (x + 2, y - 4 )
