Question 144704
As a rule, don't completely trust what a computer tells you. In this case, the simplifier you are referring to is a little strange.



{{{ -3(5-y)+2^4=18y }}} Start with the given equation



{{{ -3(5-y)+16=18y }}} Raise 2 to the 4th power to get 16



{{{-15+3y+16=18y}}} Distribute



{{{3y+1=18y}}} Combine like terms on the left side



{{{3y=18y-1}}}Subtract 1 from both sides



{{{3y-18y=-1}}} Subtract 18y from both sides



{{{-15y=-1}}} Combine like terms on the left side



{{{y=(-1)/(-15)}}} Divide both sides by -15 to isolate y




{{{y=1/15}}} Reduce

Answer:

So our answer is {{{y=1/15}}}  (which is approximately {{{y=0.0667}}} in decimal form)
