This looks like a linear equation the equation  5x - 3 = 8?
But, the options look as if the equation has to do with logs. Please clarify. Thanks.

anonymous · Answer

Yes it is solving equations with logarithms

directrix · Answer

5x - 3 = 8
5x = 11
x = 11/5.

Those steps appear to have nothing to do with the problem. I think you left something off the problem.

anonymous · Answer

The actual equation is written 5^x-3=8, my fault I thought i included it. So it actually 5 to the power of x.

directrix · Answer

5^x - 3 = 8 
The 5^x and the 3 are not like terms so it would be incorrect to subtract them and get 2^x.

c.2^x=8
