whats 4y+3
Unsolvable because you have not set the function of y equal to anything.
4y+ 3
you would do 4 timed by y, whatever number y represents, then add on 3
e.g. if y= 6
4x6=24
24+3=27
is it 4y+3=0? if so subtract 3 then add it on the other side 4y=3 then divide by 4 to isolate the variable. 4y/4=3/4 and you end up with y=3/4
