Answer :
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]
