Step-by-step explanation:
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](https://tex.z-dn.net/?f=m%2Bs%3D42)
You have 10 more math problems than science problems
![m=s+10](https://tex.z-dn.net/?f=m%3Ds%2B10)
substitute s+10 for m in the first equation
![m+s=42](https://tex.z-dn.net/?f=m%2Bs%3D42)
![s+10+s=42](https://tex.z-dn.net/?f=s%2B10%2Bs%3D42)
![2s+10=42](https://tex.z-dn.net/?f=2s%2B10%3D42)
subtract 10 from both sides
![2s = 32](https://tex.z-dn.net/?f=2s%20%3D%2032)
divide both sides by 2
![s= 16](https://tex.z-dn.net/?f=s%3D%2016)
![m=s+10](https://tex.z-dn.net/?f=m%3Ds%2B10)
![m=16+10](https://tex.z-dn.net/?f=m%3D16%2B10)
![m=26](https://tex.z-dn.net/?f=m%3D26)
number of math problems = 26
number of science problem = 16
