Answer:

x = 9

y = -10

Step-by-step explanation:

2x + y = 8

Subract 2x from both sides to get y = 8 - 2x.

-10x - 8(8 - 2x) = -10

-10x - 64 + 16x = -10

6x - 64 = -10

6x = 54

x = 9

2(9) + y = 8

18 + y = 8

y = -10

Step-by-step explanation:    

Step 1: Isolate x for -10x - 8y

[tex]\begin{bmatrix}2\left(-\frac{-5+4y}{5}\right)+y=8\end{bmatrix}[/tex]

Step 2: Simplify

[tex]\begin{bmatrix}\frac{10-3y}{5}=8\end{bmatrix}[/tex]

Step 3: Substitute y=-10

[tex]x=-\frac{-5+4\left(-10\right)}{5}[/tex]

Step 4: Solve

[tex]x=9[/tex]

ANSWER: [tex]x=9,\:y=-10[/tex]
