-- Pick any number at all and call it " x " . Any number whatsoever.
-- Multiply it by 8 and call the product " y " .
-- There you are ! Now you have an ordered pair that's a solution to that equation.
There's no limit. You can keep inventing ordered pairs just like that, until
you have millions or billions of them, or as many as you want.

∙ 11y agox=7 and y=4
X= -1/4. Y= -2/5. ( -.25, -0.4 )
Solving by the elimination method: x = 7 and y = 2
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
x=4, y=9 (4,9)
Y-8x plus 9y equals 10y-8x.
No.
x=7 and y=4
-8x-8y=-64 -8y=8x-64 y=-x+8
X= -1/4. Y= -2/5. ( -.25, -0.4 )
Solving by the elimination method: x = 7 and y = 2
If: y = 8x+7 then the y intercept is 7 and the slope is 8
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
Complementary angles add up to 90 degrees so if y = 8x-20 degrees then the complement of y is 90 - (8x - 20) = 110 - 8x degrees.
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
x=4, y=9 (4,9)
When 5x+3 = 17 then x = 2.8 Therefore when 8x-y = 3 then x = 2.8 and y = 19.4
