elena-14-01-66 [18.8K]

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

m+s=42

You have 10 more math problems than science problems

m=s+10

substitute s+10 for m in the first equation

m+s=42

s+10+s=42

2s+10=42

subtract 10 from both sides

2s = 32

divide both sides by 2

s= 16

m=s+10

m=16+10

m=26

number of math problems = 26

number of science problem = 16
