math trouble

posted by .

I have 2 problems I need help with using either substitution or elimination method what is the solution set of 3x -2y = -4 and 5x = 2y? Second, Given: log sub a 2 = .4, log sub a 3 = .5, log sub a 5 = .8 what is the value of log sub a .01?

On the first, I will gladly critique your work.

Secondly, note that
loga 10= loga 2 + loga5
loga 1 = 0
loga .1= - loga 10
loga .01 = - 2loga 10

the answer is none YOU can get the answer by listening to Radio Disney or playing BIG Brain Accamady On a Nintendo Ds
