Solve by elimination 5x-14y=22 -6x+7y=3
Airida [17]
5x - 14y = 22 ⇒   5x - 14y = 22
-6x + 7y =  3  ⇒ <u>12x - 14y = -6</u>
                                    <u>-7x</u> = <u>28</u>
                                     -7     -7
                                       x = -4
                            5x - 14y = 22
                         5(-4) - 14y = 22
                           -20 - 14y = 22
                         <u>+ 20           + 20</u>
                                  <u>-14y</u> = <u>42</u>
                                  -14    -14
                                       y = -3
                                  (x, y) = (-4, -3)

Point P is located at (-3,5)
Naya [18.7K]

Answer:

P' (- 7, - 5 )

Step-by-step explanation:

A translation of 3 units to the left means subtractin 3 from the x- coordinate with no change to the y- coordinate, thus

P(- 3, 5 ) → (- 3 - 4, 5 ) → (- 7, 5 )

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), thus

(- 7, 5 ) → P'(- 7, - 5 )
