Answer:

x = -17

Step-by-step explanation:

-42 + 3x = 60 + 9x

3x = 60 + 42 +9x

3x = 102 + 9x

-9x + 3x = 102

-6x = 102

x = -17

Which of the following ordered pairs are solutions to the equation y=−2x+6? (Select all that apply.) Select all that apply: (0,6
yuradex [85]

Answer:

(0,6)

(1,4)

Step-by-step explanation:

(0,6)

1. Plug in 0 for x and solve to see if 6 results for y

y = -2(0) + 6

0 + 6 = 6

y = 6

When 0 is plugged in for x, y equals 6 which makes (0,6) a solution.

(1,4)

1. Plug in 1 for x and solve to see if 4 results for y

y = -2(1) + 6

-2 + 6 = 4

y = 4

When 1 is plugged in for x, y equals 4 which makes (1,4) a solution.

(-2,-2)

1. Plug in -2 for x and solve to see if -2 results for y

y = -2(-2) + 6

4 + 6 = 10

10 ≠ -2

When -2 is plugged in for x, y does not equal -2 which means (-2,-2) is not a solution.
