Question

4х-2у-7=0 3х+2у-14=0 ​

Answer 1

Ответ:

1 ответ это 7 а второй 14

Answer 2

To solve the system of equations:

1. 4x - 2y - 7 = 0
2. 3x + 2y - 14 = 0

You can use the method of elimination. Adding the two equations together will eliminate the "y" terms:

(4x - 2y - 7) + (3x + 2y - 14) = 0

Now, combine like terms:

4x + 3x - 2y + 2y - 7 - 14 = 0

This simplifies to:

7x - 21 = 0

Now, add 21 to both sides of the equation:

7x = 21

Finally, divide both sides by 7 to isolate "x":

x = 21 / 7 x = 3

Now that you have the value of "x," you can substitute it back into either of the original equations to solve for "y." Let's use the first equation (4x - 2y - 7 = 0):

4(3) - 2y - 7 = 0

12 - 2y - 7 = 0

Combine like terms:

12 - 7 = 2y

5 = 2y

Now, divide both sides by 2 to solve for "y":

2.5 = y

So, the solution to the system of equations is x = 3 and y = 2.5.
