Solve the system of equations by substitution. What is the product of x and y from the solution? 2x + 3y = 12 5x − y = 13
Darina [25.2K]

2x + 3y = 12 (1st)

5x − y = 13 (2nd) ---> y = 5x - 13


Substitute y = 5x - 13 into (1st) equation


2x + 3(5x - 13) = 12

2x + 15x - 39 = 12

17x - 39 = 12

17x = 51

x = 3


substitute x = 7 into y = 5x - 13

y = 5x - 13

y = 5(3) - 13

y = 15 - 13

y = 2


Answer

solution x = 3 and y = 2

Hello,

Question:

Keisha solved the following equation:

4x − 2x + 8 = 6(x + 4)

Which step has an incorrect justification? (Make sure to type only the number of the step into the blank: 1, 2, 3, 4 or 5)

Correct Solution:

x − 2x + 8 = 6(x + 4)

4x + −2x + 8 = (6) (x) + (6) (4) (Distribute)

4x + −2x + 8 = 6x + 24

(4x + −2x) + (8) = 6x + 24 (Combine Like Terms)

2x + 8 = 6x + 24

2x + 8 = 6x + 24

Subtract 6x from both sides.

2x + 8 − 6x = 6x + 24 − 6x

−4x + 8 = 24

Subtract 8 from both sides.

−4x + 8 − 8 = 24 − 8

−4x = 16

-4 x -4 = 16

x = -4

Answer:

Where keisha went wrong was forgeting to subtract 6x to both sides.

Incorrrect step is #3
