Answer:
number of math problems = 26
number of science problem = 16
Step-by-step explanation:
a total of 42 math and science problems for homework
Let m be the number of math problems and 's' be the number of science problems
You have 10 more math problems than science problems
substitute s+10 for m in the first equation
subtract 10 from both sides
divide both sides by 2
number of math problems = 26
number of science problem = 16
Well, if you do this in reverse
23+17 = 40
40-23 = 17
40 would be your answer.
