Answer:
y= 9/2x - 11/2
or
y=4.5x -5.5
Explanation:
To solve for y, we must get y by itself on one side of the equation.
9x-2y=11
9x is being added to 2y. The inverse of addition is subtraction. Subtract 9x from both sides.
9x-9x -2y= 11-9x
-2y= 11-9x
y is being multiplied by -2. The inverse of multiplication is division. Divide both sides by -2.
-2y-/2= 11-9x/-2
y= 11/-2 - 9x/-2
y=- 11/2 +9/2 x
or
y= -5.5 +4.5 x
Reorder the terms.
y= 9/2x - 11/2
or
y=4.5x -5.5
