7-7 (-8+x)=-14+4×
7+56-7x=-14+4x
63-7x=-14+4x
add 7x to both sides
63=-14+11x
add 14 to both sides
77=11x
divide both sides by 11
7=x
therefore 7 is x
The answer is: Yes 10-2x is less than 10, x= -5

Answer:
b = 14.6
Step-by-step explanation:
From the looks of it, this is law of sines.
So I'll set it up like so:
b / sin(90) = 12 / sin(55)
b / sin(90) = 14.649
b = 14.6
