How would you rearrange the equation 4 equals 2 over 3 log x minus 0.9 to find x?

Without brackets, there are many ambiguities in the question.
4 = 2/3*log(x) - 0.9
4.9*3/2 = logx
7.35 = logx
so x = 107.35
However, the original equation could also have referred to
4 = 2/3*log(x-0.9)
or
4 = 2/[3*log(x)] - 0.9
or
4 = 2/[3*log(x-0.9)]

What is the number that you would multiply one or both of the equations -4 equals 5y equals 6 -6x-y equals 8?
There is no need. The first equation can be rearranged to a simple equation in just y. Multiply it by 0.2 to solve for y. Substitute the value of y in the second equation and rearrange to get a simple equation in x. Multiply by (1/6) to find x.
