Question

0.01x - 0.3y = 1
y = 0.1x - 2
What is the solution of the given system?
(-20, -4)
(0.4, 2)
(0, 20)

Answer 1

Again, plug in the y value into the first equation, and then solve for x using the y value in either of the equations after.

Answer 2

0.01x - 0.3(0.1x-2) = 1
and then use that x value to get y.

Answer 3

Do you understand?

Answer 4
