Answer:  x=1;y=1 or (1,1)

Step-by-step explanation:

You can apply the Method of substitution.

Knowing that  x = 2y - 1 (second equation), you can substitute it into the first equation and solve for the variable y:

2x+y=3\\2(2y - 1)+y=3\\4y-2+y=3\\5y=3+2\\5y=5\\y=1

Now you need to substitute y=1 into the second equation x = 2y - 1 to calculate the value of the variable x. Then:

x = 2(1) - 1\\x=2-1\\x=1

Then, the solution is:

x=1;y=1 or (1,1)

If i^2 = −1 and x = i + 9, which is the result of squaring x?
Anestetic [448]

Answer:

80 + 18i

Step-by-step explanation:

i² = -1

x = i + 9

x² = (i + 9)²

Applying; (a + b)² = a² + 2ab + b² concept,

x² = i² + 18i + 81

We know that i² = -1

So x² = -1 + 18i + 81

x² = 81 - 1 + 18i = 80 + 18i
