Question

Could someone help me? Which color is it.

Answer 1

(1,3)

Explanation:

y = 2x+1

y = 4x-1

Since both equations are equal to y, we can set them equal to each other

2x+1 = 4x-1

Subtract 2x from each side

2x+1-2x = 4x-2x-1

1 = 2x-1

Add 1 to each side

1+1 = 2x-1+1

2 = 2x

Divide each side by 2

2/2 = 2x/2

1 =x

Now we need to find y

y = 2x+1

y = 2(1)+1

y =3
