Solution 1: 5x + 2y = 3  

Solution 2: 3x - 2y = 5

Graphic Organizer: 2(y) + 5(x) = 3
-2(y) + 3(x) = 5

The value of 'x' in solution 2

3(x) = 2(y) + 5
x = 2(y)÷ 3 + 5÷3

The value of 'y' in solution 1

5(2(y))÷3+5÷3 + 2(y) = 3  
16(y)÷3 = -16÷3  
16(y) = -16

y-intercept ➡ -1

x-intercept in both of The solutions!
(2÷ 3)(-1)+5÷ 3 = 1 

x-intercept : 1
y-intercept : -1

Your answer would have to be

(1, -1)

Reduce 27/42 to the lowest term
wel
So you need to find a number that goes into both of these numbers:
3 goes into both, so divide both by 3
27/3 = 9
42/3 = 14
so your answer is 9/14

Ms. Lee wrote a test with 15 multiple choice short answer questions. The multiple choice questions x are worth 5 points and the
hram777 [196]

x + y = 15 and 5x + 10y = 100 are the system of equations that represent this situation

<em><u>Solution:</u></em>

Let "x" be the number of multiple choice questions

Let "y" be the number of short answer questions

Worth of 1 multiple choice questions = 5 points

Worth of 1 short answer question = 10 points

<em><u>Ms. Lee wrote a test with 15 multiple choice short answer questions</u></em>

Therefore,

number of multiple choice questions + number of short answer questions = 15

x + y = 15 -------- eqn 1

<em><u>The maximum number of points possible on the test is 100</u></em>

Therefore, we frame a equation as:

number of multiple choice questions x Worth of 1 multiple choice questions + number of short answer questions x Worth of 1 short answer question = 100

x \times 5 + y \times 10=100

5x + 10y = 100 ------- eqn 2

Thus eqn 1 and eqn 2 are the system of equations that represent this situation
