Cross multiply to get 8k+24=56 then solve for k so subtract 24 from each side to get 8k=32 so k=4
I think 8. Plug in -4 for x. 1/2-4^2
Using pemdas -4^2 is 16 and 1/2•16 is 8. If there were parenthesis around 1/2x then 1/2•-4 would be -2 and -2^2 is 4 but since there aren’t parentheses then 8

4x-28 = x + 2
4x=x+30
3x=30
x=10
