Answer: -1/7
Step-by-step explanation:
10x+2-2x=2-6x-2
=10x-2x=-6x-2
=8x=-6x-2
=8x+6x=-2
14x=-2
x=-2/14
x=-1/7
Sin^-1(5/13) = 22.6
sin(22.6/2) = 0.196
1/2 + 1/2 + 2/3 + 3/4 + 47/48 + 48/49 +49/50 = 5.35542517007
This decimal form is ≈ to 5 2/5
Sum means addition so the equation is x+5=14
To get the answer, just do 14-5 and the answer is 9
