Written as a single function is sin(20+30) which is sin(50deg)
First you have to find common denominators for all the Fractions. (witch should be 24 for the denominators) Then add 6 21/24 + 1 12/24 = 8 9/24, Then take 8 9/24 - 3 4/24 and you should get the answer 5 5/24
<span>3(7x+ 1) = 21
21x + 3 = 21
21x = 18
x = 6/7
hope this helps!</span>
