Fid the root of each question

Question

1. 1/3 (2w-6) = -10

2. 3a-7/4 = 4a+5/3

3. 3k/2 - k+3/3 = 8- k+2/4

Answer 1

I will do one, then be happy to check you on the others.

2) subtract 4a from each side
3a-4a-7/4=4a-4a+5/3
-a-7/4=5/3
add 7/4 to each side
-a=5/3+7/4= 20/12+21/12=41/12
a= -41/12
