This equation of the recipe can be represented as y = x + 5.5 and The constraints are x is ≥ 0 and y is ≥ 5.5.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Otto used 5.5 cups of whole wheat flour and x cups of white flour in the recipe.
The total amount of flour (y) = the total amount of whole wheat flour (5.5) + the total white flour (x).
Therefore, the equation is:
y = x + 5.5
The possible values are
x = 0 or greater to it since the minimum amount of white flour that can be added is 0.
y = 5.5 or greater to it since even if no
white flour is added the minimum total is 5.5.

Answer and Step-by-step explanation:
2/3 (3x + 9) = -2(2x + 6)
Step by step
2/3 * 3x and 2/3 * 9 = 2x and 6
which is 2x + 6 (since 6 is a positive put a plus 6 [ + 6 ] )
-2 * 2x and -2 * 6 = -4x and -12
which is -4x - 12 (since 12 is negative put a minus 12 [ - 12 ])
We now have 2x + 6 = -4x - 12
now add 4x on both sides
2x + 6 + 4x = −4x − 12 + 4x
6x + 6 = −12
now Subtract 6 from both sides.
6x + 6 − 6 = −12−6
6x=−18
finally Divide both sides by 6.
6x/6 = -18/6
x = -3
The answer is x=−3
2/3, 12/18, and 24/36 should be okay.
