(x, y) = (1, 2)

Step-by-step explanation:

y = 2x

3x + 4y = 11

3x + 4(2x) = 11

3x + 8x = 11

11x = 11

x = 1

So, y = 2.

do you have the measurements?

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
