I have to say a because the problem is continuing
Steps to solve:
-6w - 8 + 15w = 2w - 8 + 7w
~Combine like terms
9w - 8 = 9w - 8
~Add 8 to both sides
9w = 9w
~Divide 9 to both sides
0 = 0
All real numbers are solutions.

Best of Luck!
x=15-657/2=15-373/2=-5.316
x=15+657/2=15+373=20.316
Answer:
For the first
Since the angles in a triangle sum up to 180.
We already have angleA 41° and angleC 90°
To get the remaining angle B 180-(41+90)=49°
Now
We apply sine rule to solve
Divide each term you pick by the Sine of the angle directly opposite it.
So We have
4/Sin41° = X/Sin49
Making X subject..
X= 4Sin49/Sin41
X=4.601
To the nearest tenth
X= 4.6.
For the second question
Applying the same concept
Angle B = 180-(90 + 47) = 43°
Applying Sine Rule
X/Sin43 = 3/Sin90
Making x subject
X= 3Sin43/Sin90
X=2.04
To the nearest Tenth
X=2.0
