Answer:

x = -2

y = -1

Step-by-step explanation:

y - 2x = 3 and y - x = 1

Subtract the second equation from the first

   y - 2x = 3

- ( y -  x  = 1)

––––––––––

       -x = 2

Multiply both sides by -1

x = -2

Sustitute x = -2 into the first equation

y - 2(-2) = 3

y + 4 = 3

Subtract 4 from both sides

y = -1

How does this work?????
ankoles [38]

Answer:

x = 4\sqrt{5}

Step-by-step explanation:

Since the triangle is right, solve for x using Pythagoras' identity, that is

x² = 8² + 4² = 64 + 16 = 80

Take the square root of both sides

x = \sqrt{80} = \sqrt{16(5)} = \sqrt{16} × \sqrt{5} = 4\sqrt{5} ← exact value
