Question

2x – 3y = 235x + 3y = 26​

Answer 1

Ответ:

7x=49

x=7

2×7-3y=23

21-3y=23

3y=21-23

3y=-2

y=-2/3

Answer 2

You have a system of two linear equations:

1. 2x - 3y = 23
2. 5x + 3y = 26

You can solve this system of equations using either the substitution method or the elimination method. Let's use the elimination method:

First, add the two equations together to eliminate the variable "y":

(2x - 3y) + (5x + 3y) = 23 + 26

This simplifies to:

7x = 49

Now, divide both sides by 7 to solve for "x":

7x/7 = 49/7

x = 7

Now that you have found 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:

2x - 3y = 23 2(7) - 3y = 23 14 - 3y = 23

Subtract 14 from both sides:

-3y = 23 - 14 -3y = 9

Now, divide both sides by -3 to solve for "y":

(-3y)/(-3) = 9/(-3)

y = -3

So, the solution to the system of equations is:

x = 7 y = -3
