Answer:
Step-by-step explanation:
y = x - 5 ← x - 5 can be subbed for y in the second equation, as shown:
3x - y = 7 → 3x - (x - 5) = 7, or 2x + 5 = 7, or 2x = 2, or x = 1.
Subbing 1 for x in the first equation, we get y = 1 - 5 = -4,
and so the solution is (1, -4).
Second system:
2x + 2y = 12
3x + y = 2
Let's eliminate y first. Mult. the 2nd equation by -2, obtaining:
2x + 2y = 12
-6x - 2y = -4
--------------------
-4x = 8, and so x = -2. Subbing -2 for x in the 2nd equation, we get:
3(-2) + y = 2, or -6 + y = 2, or y = 8
Then the solution to the second system of equations is (-2, 8).

The baker make should make 5 trays of corn muffin and 2 trays of bran muffin to maximize his profit
<h3>How to determine how many trays of each type of muffin should the baker make to maximize his profit?</h3>
The given parameters can be represented in the following tabular form:
Corn Muffin (x) Bran Muffin (y) Total
Milk 8 4 48
Wheat flour 5 5 35
Profit 5 3
From the above table, we have the following:
Objective function:
Max P = 5x + 3y
Subject to:
8x + 4y <= 48
5x + 5y <= 35
x, y > 0
Express the constraints as equations
8x + 4y = 48
5x + 5y = 35
Divide 8x + 4y = 48 by 4 and divide 5x + 5y = 35 by 5
So, we have:
2x + y = 12
x + y = 7
Subtract the equations
2x - x + y - y = 12 - 7
Evaluate
x = 5
Substitute x = 5 in x + y = 7
5 + y = 7
This gives
y = 2
So, we have
x= 5 and y = 2
Hence, the baker make should make 5 trays of corn muffin and 2 trays of bran muffin to maximize his profit
