Answer 1

Ответ:

We can use the method of substitution to solve for x and y. From the first equation, we can solve for y:

y = 5 -11x

Then we can substitute this expression for y in the second equation:

3x - 2(5 - 11x) = 40

Simplifying:

3x - 10 + 22x = 40

2511x

Now we can substitute this expression for y in the second equation:

3x - 2(5 - 11x) = 40

Simplifying this equation, we get:

3x - 10 + 22x = 40

25x = 50

x = 2

Now we can substitute this value for x in the first equation to solve for y:

11(2) + y = 5

y = -17

Therefore, the solution to the system of equations is x = 2 and y = -17.
