Answer:

The correct answer is (5, -4)

Step-by-step explanation:

To solve using substitution, we can take the second equation (y = -3x + 11) and use the value of y to replace y in the first equation. This will allow us to solve for x.

3x + 2y = 7

3x + 2(-3x + 11) = 7

3x - 6x + 22 = 7

-3x + 22 = 7

-3x = -15

x = 5

Now that we have that value, we can put it in for x in either equation and solve for y.

y = -3x + 11

y = -3(5) + 11

y = -15 + 11

y = -4

Therefore the correct answer is (5, -4)

Hi, Hagrid :) Thanks for posting your question here at Brainly. I hope I could help you with this problem.

The incorrect reason would be letter A: add c/a to both sides.
What he did was transpose the term c/a from the left to the right so that he could separate the terms with variables to the left hand side and the constants in the right hand side.

Which number line shows the solution of -3x + 6 > 12

olga_2 [115]

Answer:

x < -2

Step-by-step explanation:

subtract 6 from each side

-3x > 6

divide both sides by -3

x < -2

(with inequalities you must flip the sign if you divide by a negative number)
