To answer this question, you should set up and equation before doing anything else. So for this question you 're going to set up two equations.

The first equation is 2x+5y=33

The second equation is 8x+3y=30

Once you do that you have to solve for either X or Y by canceling out the other one. In this problem figuring out the Y is easier because you can cancel the X's more easily than the Y. To cancel a variable, they have to add up to 0.

So to cancel the X you multiply the equation 2x+5y=33 by -4.

That gives you -8x-20y= -132

Then you set up the two equations and add them together.

(-8x-20y= -132) + (8x+3y=30)

That gives you -17y = -102

So then you solve for Y by dividing by -17. You find out that Y is equal to 6. Then you plug the 6 back into the ORIGINAL equations and solve for X, which turns out to be 1.5

Hope this helped and if you get confused or have questions please ask :)

Prove that the value of the expression: 731^2−631^2 is divisible by 100
Ivanshal [37]

Answer:

Step-by-step explanation:

731² - 631² is the difference of squares.

731² - 631² = (731+631)(731-631) = 1362×100

therefore, 731² - 631² is divisible by 100

What is the answer to - 5y = - 5 and. 7x +6y=7
Vikentia [17]

Answer:

(1/7, 1)

Step-by-step explanation:

By "answer," you probably meant "solution."  What is the "solution of the system of linear equations

- 5y = - 5

+ 7x +6y=7

The first eqation can be solved for y:  y = 1.  Substitute 1 for y in the secon equation.  Then 7x + 6(1) = 7, or 7x = 1, or x = 1/7.

The solution to this system is (1/7, 1)

What is the midpoint of a line segment with endpoints at<br> (-3.5, -2.1) and (5.7,3.3)?
Tanzania [10]

Answer:

(1.1 , 0.6)

Step-by-step explanation:

midpoint (x , y): ( x+x') /2 , (y+y') / 2

x = (-3.5 + 5.7) / 2 = 2.2 / 2 = 1.1

y = (-2.1 + 3.3) / 2 = 1.2 / 2 = 0.6

What is the answer to - 3/7 m=12
Triss [41]
Solve for m:
(-3 m)/7 = 12

Multiply both sides of (-3 m)/7 = 12 by -7/3:
(-7 (-3) m)/(3×7) = (-7)/3×12

(-7)/3×(-3)/7 = (-7 (-3))/(3×7):
(-7 (-3))/(3×7) m = (-7)/3×12

(-7)/3×12 = (-7×12)/3:
(-7 (-3) m)/(3×7) = (-7×12)/3

(-7)/7 = (7 (-1))/7 = -1:
(-3-1 m)/3 = (-7×12)/3

(-3)/3 = (3 (-1))/3 = -1:
--1 m = (-7×12)/3

(-1)^2 = 1:
m = (-7×12)/3

12/3 = (3×4)/3 = 4:
m = -74
-7×4 = -28:
Answer: m = -28
