Question

Solve this system of equations

{y = 2x
{x = -y + 6

Answer 1

the answer is x=2 and y=4

Answer 2

x = 2

y = 4

Explanation:

y = 2x ---------> (1)

x = -y + 6 ------> (2)

Now you can put 2x instead of y to the equation (2) and find the value of x.

Let us solve.

x = -y + 6

x = -2x + 6

x + 2x = 6

3x = 6

Divide both sides by 3.

x = 2.

And now we can find the value of y by replacing x with 2.

For that let us take equation (1).

* You can take either equation (1) or (2) to find the value of y.

Let us solve now.

y = 2x

y = 2 × 2

y = 4

There fore,

x = 2

y = 4

Hope this helps you.
