please help me figure out how to do thes problems
4. y/2+5=12
6. x/39=0
7. 14+h/5=2
THIS IS IMPROTANT Y/2, X/3 AND H/5 ARE FRACTIONS. it doesnt mean divide its fractions that's why i need help plse tell me how you did it so i can figure out the rest of my problmes

Well, actually fractions and divide are pretty similar.
now for example
(y/2) + 5 = 12
add 5 to both sides
(y/2) +0 = 17
multiply both sides by 2
y = 34 
thx you so much i was so confused

4. y/2 + 5 = 12 (use the inverse operation to get rid of the 5)
y/2+5(5)= 12 (5)
y/2=17 (isolate the variable, aka, multiply both sides by 2, to get your answer of...)
y= 34
