Answer:

Answer is "B"

Step-by-step explanation:

Rearrange terms: 7-2x=9x+19

-2x+7=9x+19

Subtract 7 from both sides of the equation: -2x+7=9x+19

-2x+7-7=9x+19-7

Simplify: -2x=9x+12

Subtract 9x from both sides: -2x=9x+12

-2x-9x=9x+12-9x

simplifiy: -11x=12

solution: x=-12/11

Is the point (8, -3) a solution to the linear equation 2x + 3y = 12

Answer:

No, (8, -3) is not a solution.

Step-by-step explanation:

2x + 3y = 12

(substitute the variables for the point; x = 8 & y = -3)

2(8) + 3(-3) = 12

16 - 9 = 12

7 ≠ 12
