Solve the system of equations given below.
eduard

Answer:

The system of this equation is ( -1, 10) which is Option A.

Step-by-step explanation:

Solve for y in the first equation.

y =  - 5x + 5 \\  - 2y =  - x - 21

Replace all occurrences of yy with -5x+5 in each equation.

10x - 10 =  - x - 21 \\ y =  - 5x + 5

Solve for x in the first equation.

x =  - 1 \\ y =  - 5x + 5

Replace all occurrences of x with -1 in each equation.

y = 10 \\ x  =  - 1

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−1, 10)

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>system</u><u> </u><u>of</u><u> </u><u>this</u><u> </u><u>equation</u><u> </u><u>is</u><u> </u><u>(</u><u>-1</u><u>,</u><u> </u><u>10</u><u>)</u><u>.</u><u> </u>

<u>Option</u><u> </u><u>A</u><u>.</u>
