Answer:

Science problems= 12

Math problems= 27

Step-by-step explanation:

If

x= math problems for solving

y= science problems for solving

x+y=39

y=x-15

Using substitution method:

x+(x-15)=39

2x-15=39

2x=39+15

x=(39+15)/2

x=27

Having "x" lets find out "y" value.

x+y=39

27+y=39

y=39-27

y=12
