Answer:

this is the he answer according to the information given

The work of a student to solve a set of equations is shown:Equation 1: m = 8 + 2n
Equation 2: 3m = 4 + 4n


Step 1:
−3(m) = −3(8 + 2n) [Equation 1 is multiplied by −3.]
3m = 4 + 4n [Equation 2]

Step 2:
−3m = −24 − 6n [Equation 1 in Step 1 is simplified.]
3m = 4 + 4n [Equation 2]

Step 3:
−3m + 3m = −24 − 6n + 4n [Equations in Step 2 are added.]

Step 4:
0 = −24 − 2n

Step 5:
n = −12

In which step did the student first make an error?

Step 1

Answers

The student first makes an error in the Step 3 where he addsequations in Step 2 to use the elimination method.

What is the elimination method?

To create an equation in one variable using the elimination method, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.

How to solve this problem?

Notice that the student uses the elimination method to solve the equations. In Step 1, he makes the coefficients of m equal in both equations. In Step 2, he simplifies the previous step. In Step 3, he wants to add both equations to create an equation in one variable. But He forgot to add 4 of Equation 2. It's a mistake.

Therefore the student first makes an error in the Step 3 where he addsequations in Step 2 to use the elimination method.

3. this is because you added un equal amounts to both sides.

Factorise x² + 4x + 3.I understand everything perfectly until I have to split the two sections, add up and pull out the common factors:

x² + 3x: common factor is x
1x + 3: common factor is 1

From here I do not understand how you get to the answer which I do know is (x + 1) • (x + 3).

None of the explanations out there give detail to this step. I don’t understand how adding those two groups up (while pulling out common factors) will give you (x + 1) • (x + 3)!

I would hugely appreciate any help on this! Thank you :)
