Solve the system of equations.
13x – 6y = 22
x = y + 6

Step-by-step explanation:

Replace x in the first equation.

Now replace y in any of the equations to find x.

x = -2

y = -8

Step-by-step explanation:

13x – 6y = 22

x = y + 6

x - y = 6

Elimination

13x - 6y = 22 | ×1 |

x - y = 6 | ×6 |

13x - 6y = 22

6x - 6y = 36

--

7x = -14

x = -14/7

x = -2

Subsitution

x - y = 6

-2 - y = 6

-y = 6 + 2

-y = 8

y = -8

mr. graef told us it is 13 pints

step-by-step explanation:

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
