Question

Solve the system by the elimination method. *-8x + 2y = –10–2x + 2y =-10(4,-3)(0,-5)(-3,4)(2,-4)

Answer 1

-8x + 2y = –10

–2x + 2y =-10

Subtracting the equations, we get:

-8x + 2y - (-2x + 2y) = -10 - (-10)

-8x + 2y + 2x - 2y = -10 + 10

-6x = 0

x = 0

Replacing in the first equation:

-8(0) + 2y = -10

2y = -10

y = -10/2

y = -5

Then, the answer is (0, -5)
