Which of the following ordered pairs represents a solution to the equation below?
y=3x- 2
choose 1
(-2,-8)

(-1,-6)
(0, -3)
(1,0)
(2,2)

(-2,-8)

Step-by-step explanation:

For these types of questions they are very easy. The first thing to know is the points. For this case, we will start off with (1,0) The x is 1 and the y is 0 so you plug them in the equation. You will then get 0=3(1)-2. Once you simplify that you will get 0=1 which is wrong. For the correct answer, the formula will look like this -8=3(-2)-2 which then simplify to -8=-8 which is true.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
