Use addition to solve the linear system of equations. Include all of your work in your final answer. x-y=6 y=x-4

no solutions

Step-by-step explanation:

x-y=6

y=x-4

Subtract x from each side

-x+y = x-4-x

-x+y = -4

Add this to the first equation

x-y=6

-x+y = -4

0x + 0y = 2

0=2

This is never true so there are no solutions

No solutions.

Step-by-step explanation:

x - y = 6

y = x - 4

Solve for x in the first equation.

x = 6 + y

Put x as 6 + y in the second equation and solve.

y = (6 + y) - 4

y - y = 6 - 4

0 = -2

There are no solutions.

idk

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600
