Answer 5

I think you mean 'a'

Is the equation \[\large \frac{a}{2}=\frac{a-4}{30}\]

or is it

\[\large \frac{a}{2}=a-\frac{4}{30}\]

Answer 6

bring all a's to one side

Answer 7

the first one jim

Answer 8

30 * a = 2*(a-4)
30x = 2a - 8
28a = -8
a = -8/28
a = -2/7

Answer 9

k thx

Answer 10

how do i move the a's?

Answer 11

\[\large \large \frac{a}{2}=\frac{a-4}{30}\]


\[\large \large 30a=2(a-4)\]


\[\large \large 30a=2a-8\]


\[\large \large 30a-2a=-8\]


\[\large \large 28a=-8\]


\[\large \large a=-\frac{8}{28}\]


\[\large \large a=-\frac{2}{7}\]

Answer 12

subtract 2a. so 30a=2a-8, 30a-2a=-8, 28a=-8 got that much/
