Question

Let's practice! As an exercise in dealing with UAS, you get 42 math and science assignments to do at home. The math assignments that you get are 10 questions more than the science questions. How many questions for each subject? Use the system of linear equations to check your answers.

Answer 1

Answer: there were 26 questions for math subjects and 16 questions for IPA subjects.

Step-by-step explanation:

Two Variable Linear Equation System

Known :

Mathematics and Ipa = 42 questions

Mathematics = 10 questions more than Ipa

Asked: Many questions after each subject

Settlement:

For problems like this, we can use the Two Variable Linear Equation System (SPLDV) method. There are 4 ways, 2 of which are elimination which is eliminating one variable, and the other is substitution.

•••••••••••••••••••••••••••••••••••••••••••••••

We suppose:

Mathematics = m

Ipa = i

We know the form becomes its mathematical model:

Equation 1

Mathematics and IPa = 42 questions

m + I = 42

Equation 2

Mathematics = 10 questions more than Ipa

m = 10 + i

m - i = 10

So we eliminate the results

m + i = 42

m - i = 10

------------ - -

2i = 32

I = 16

So, many Ipa questions are 16

Then, enter the value I into one of the equations

 

m = 10 + i

 

m = 10 + 16

m = 26

Conclusion ••••••••••••••••••••

So, there are 26 questions for math subjects and 16 questions for IPA subjects.
