Question

What is the solution of the system of equations? y = 25x + 100; y = -10x +

30 *
O A. (2,50)
O B. (-2, 10)
C. (-2, 50)
O D. (2,150)

Answer 1

B. (-2, 10) that’s the answer

Answer 2

B(-2, 10)

Explanation:

-10x+30=25x+100

subtract 25 from -10 (make it -25)

-35x+30=100

subtract 30 from 100 (make it -30)

-35x=70

divide by -35

x=-2

Plug it in:

-10(-2)+30

-20+30

y=10
