Answer 2

To solve this system of equations for x and y, you can use the method of substitution. First, let's solve the second equation for y:

у - 4 = 2(х - 2)

Now, distribute the 2 on the right side:

у - 4 = 2x - 4

Next, add 4 to both sides of the equation to isolate у:

у = 2x

Now, you can substitute this expression for y into the first equation:

3x - 4 = 6 - у

Replace у with 2x:

3x - 4 = 6 - 2x

Now, let's isolate x on one side of the equation. Add 2x to both sides:

3x + 2x - 4 = 6

Combine like terms:

5x - 4 = 6

Now, add 4 to both sides to isolate 5x:

5x = 6 + 4 5x = 10

Finally, divide by 5 to solve for x:

x = 10 / 5 x = 2

Now that you have found the value of x, you can find y using the equation у = 2x:

у = 2 * 2 у = 4

So, the solution to the system of equations is x = 2 and у = 4.
