Question

What is the solution to the system of equations?

y = -5x + 3
y=1
(0.4. 1)
(0.8.1)
(10.4)
(1.0.8)

Answer 1

(2/5, 1)

Explanation:

We are told that y = 1, so we can immediately discard the last two possible answers. Next, replace y with 1 in y = -5x + 3, obtaining 1 = -5x + 3.

Isolating 5x, we get 5x = 2, which leads to x = 2/5.

The solution is (2/5, 1).

Answer 2

A. 0.4, 1.
Explanation: y= -5 x 2/5 + 3.
Y = 5 x 2/5 = 2. -2 + 3 = 1.
