The solutions to the given system of equations are x = 6 and y = -5
<h3>Simultaneous linear equations</h3>
From the question, we are to solve the given system of equations
The given system of equation is
4x+5y=-1
-5x-8y=10
Multiply the <u>first equation</u> by 5 and the <u>second equation</u> by 4
5× (4x+5y=-1)
4× (-5x-8y=10)
20x + 25y = -5
-20x - 32y = 40
------------------------
0x + (-7y) = 35
-7y = 35
y = 35/-7
y = -5
Substitute the value of y into the first equation to find x
4x + 5y = -1
4x + 5(-5) = -1
4x -25 = -1
4x = -1 +25
4x = 24
x = 24/4
x = 6
Hence, the solutions to the given system of equations are x = 6 and y = -5

Step-by-step explanation:
Find all solutions for x by breaking the absolute value into the positive and negative components.
We have 4 rectangles 10 * 25 and 2 rectangles 10*10
so surface area of the bos will be 4*250 + 2*100 = 1200 cm^3
Answer: We are given:
During the first 10 days, the stock increases by $0.30 per day.
During the next 10 days, the stock decreases by $0.45 per day.
During the last 10 days, the stock increases by $0.25 per day.
We have to find total amount the stock increase over the first 10 days.
The total amount the stock increase over the first 10 days is:
Therefore, during the first 10 days the stock was increased by $3.
