What is the x-coordinate of the solution to the system of equations 3x-2y=-30 6x+3y=3

Mathematics

HACTEHA [7]4 years ago

Answer:

Explanation:

You can subtract the second equation from the first equation to eliminate y:

7x + y = 25 – 6x + y = 23: 7x – 6x = x; y – y = 0; 25 – 23 = 2

x = 2

You could also solve one equation for y and substitute that value in for y in the other equation:

6x + y = 23 → y = 23 – 6x.

7x + y = 25 → 7x + (23 – 6x) = 25 → x + 23 = 25 → x = 2

Step-by-step explanation:

A ten-inch candle is being burned at both ends. one end burns at the rate of one inch per hour; the other end, one-and-a-half in
Sergio [31]
First keep in mind that the center is 5 inches...let L and R be the left and right positions of the two flames...

L=h and R=10-1.5h  where h is in hours....

The two flames meet when L=R so we can say:

h=10-1.5h  add 1.5h to both sides

2.5h=10  divide both sides by 2.5

h=4

So the flames will meet in five hours, using either original equation we can find this position, I'll use L=h..

L=4

So the position of the flames is 4" from the end.  The questions ask how far this point is from the center so:

5-4=1"

So the flames meet 1 inch from the center.

never [62]
Hello!!

It will be the same since there is no common factor. You just need to arrange in order. 

6x^2 + 72xy - 12x + 81y^2 + 27y

Good luck :)
