Answer:
cheating is bad
Step-by-step explanation:
The sine ratio that was applied in step 2 is incorrect, therefore, the first error is in: B. step 2.
<h3>How to Apply the Sine Ratio?</h3>
The sine ratio that is applied when we want to solve a right triangle is, sin ∅ = opposite length / hypotenuse length.
In step 2, the sine ratio applied is wrong because:
- ∅ = W
- Opposite length = XZ
- Hypotenuse length = y
Thus, we should have:
sin(W) = XZ/y
The first error is in: B. step 2.

Let's solve this by substitution.
y is given by the 2nd eqn as y = (1/3)x + 7. Subst. (1/3)x + 7 into the first eqn as a replacement for y: x + 9( (1/3)x + 7) = 3.
clear out fractions by mult. all 3 terms by 3: 3x + 9x + 63 = 3
Combine like terms: 12x = -60. Then x = -5
Find y by subst. -5 for x in the 2nd equation: y = (1/3)(-5) + 7
= -5/3 + 35/3 = 30/3 = 10.
Thus, the solution (x,y) of this system is (-5,10).
