Answer 2

To find the values of 2x and y when given the system of equations:

1. 2y - 3x = -7
2. 2y + x = 2

You can solve for x and y by using either the substitution method or the elimination method. Let's use the elimination method:

First, add both equations together to eliminate the variable y:

(2y - 3x) + (2y + x) = (-7) + (2)

Combine like terms:

4y - 2x = -5

Now, you have a new equation:

4y - 2x = -5

Next, solve for x:

4y - 2x = -5

-2x = -5 - 4y

Divide both sides by -2 to isolate x:

x = (5 + 4y) / 2

Now that you have an expression for x in terms of y, you can find 2x:

2x = 2 * [(5 + 4y) / 2]

Simplify:

2x = 5 + 4y

So, 2x is equal to 5 + 4y.

Now, let's solve for y. We can use the second equation:

2y + x = 2

Substitute the expression for x:

2y + (5 + 4y) = 2

Combine like terms:

2y + 4y + 5 = 2

6y + 5 = 2

Subtract 5 from both sides:

6y = 2 - 5

6y = -3

Divide both sides by 6 to isolate y:

y = (-3) / 6

y = -1/2

So, when you solve the system of equations, you find that:

2x = 5 + 4y, where y = -1/2 2x = 5 + 4(-1/2) 2x = 5 - 2 2x = 3

Therefore, 2x = 3 and y = -1/2.
