Answer:

x= 0 , y= -8

Step-by-step explanation:

Add the 2 equations together, you would get:

9x = 0

Divide both sides by 9:

x = 0/9

x=0

Substitute the value of x in one of the equations to get the value of y, I picked the first one (5x+2y = -16)

5(0) +2y = -16

0+2y = -16

2y = -16

Divide both sides by 2:

y = -8

2y - 2y (can Lea each other our)
Add 5x + 4x = 9x
-16 + 16 = 0
9x / 0
X=0

Answer:

x = 7.7

Option B

Step-by-step explanation:

$\frac{a}{Sin~A} &=& \frac{b}{Sin~b} \\ \frac{8}{Sin~73^\circ} &=& \frac{x}{Sin~67^\circ} \\ \frac{8}{0.96} &=& \frac{x}{0.92} \\ 0.96x &=& 8 \times 0.92 \\ 96x &=& 8 \times 92 \\ 96x &=& 736 \\ x &=& \frac{736}{96} \\ x&=& \frac{23}{3} \\ &\boxed{x=7.7}&$
