Students were requested to answer a question at academics and to state what is most important for them to succeed. One which response stood out from the rest was practice. Persons who usually are successful do not become successful by being born. They work hard and perseverance their lives to succeeding. This is how you can attain your goals. the following some question and answer examples that you could simply implement to supercharge your knowledge and gain insight that will assist you to preserve your school studies.

## Question:

Solve

y= -2x + 9

y= 4x -3

## Answer:

y = -2x + 9

y = 4x – 3

y is isolated in both equations, thus you may set the expressions (-2x + 9) and (4x – 3) equal to each other and solve for x.

-2x + 9 = 4x – 3

Subtract 9 from both sides.

-2x + 9 – 9 = 4x – 3 – 9

-2x = 4x – 12

Subtract 4x from both sides.

-2x – 4x = 4x – 12 – 4x

-6x = -12

Divide both sides by -6.

-6x/-6 = -12/-6

x = 2

Substitute 2 for x into one of the original equations to find y.

y = 4x – 3 (given)

y = 4(2) – 3 (substitute)

y = 8 – 3 (multiply)

y = 5 (subtract)

Plug x- and y-values into original equations to check work.

5 = -2(2) + 9

5 = – 4 + 9

5 = 5

5 = 4(2) – 3

5 = 8 – 3

5 = 5

**Answer**:

x = 2 and y = 5; (2, 5).

From the answer and question examples above, hopefully, they are able to guide the student deal with the question they had been looking for and notice of every detail stated in the answer above. Then could simply carry out some sharing in a group discussion and also learning with the classmate with regards to the topic, so another student also has some enlightenment and still keeps up the school learning.
