What is the solution of the system of equations that contains the equation minus 3 x minus 9 y equal 18 and the equation of the
Monica [59]

Answer:

  • Infinite solutions

Step-by-step explanation:

<u>Given equation of the line:</u>

  • - 3x - 9y = 18

<u>Use two points from the graph of the second line to find its equation:</u>

  • (- 6, 0) and (0, - 2)

<u>Use double intercept form to find the equation:</u>

  • x/a + y/b = 1
  • x/ (-6) + y/(- 2) = 1
  • 2x + 6y = - 12

Now we have the system, solve it by elimination.

<u>Multiply the first equation by 2 and the second equation by 3 and add up:</u>

  • 2(- 3x - 9y) + 3(2x + 6y) = 2*18 + 3*(- 12)
  • -6x - 18y + 6x + 18y = 36 - 36
  • 0 = 0

All terms are cancelled, it means the equations are same, the lines overlap and there is infinite number of solutions.

Why does the equation 9−2x−9−16x=−14x−7−4x−11 have no solutions?
DENIUS [597]

Answer:

Because if you add 18x to both sides of the equation, you get 0 = -18

Step-by-step explanation:

When you combine like terms in the equation, you get -18x = -18x - 18. After adding 18x to both sides, you have 0 = -18. This is not true, which means that there are no solutions to the equation.
