What is the solution to this system?
equation a: -x+y=0
equation b: x=-y-10

The answer is x = -5, y = -5

Step-by-step explanation:

Use the method of elimination

Rearrange the equations

x = -y - 10 → x + y = -10

-x + y = 0

x + y = -10

Add these two equations together to eliminate the xs

2y = -10

y = -5

-x + y = 0

-x -5 = 0

-x = 5

x = -5

(-5,-5) Is the solution

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
