The first thing we must do for this case is to define variables.
We have then:
x: weight of the big box
y: weight of the small box.
We now write the system of equations that models the problem:

We apply the graphic solution.
For this, the solution will be the cut point of both lines.
We have then that the solution occurs for the point:
Note: see attached image
Answer:
Weight of each large box: 15.5 Kilograms
Weight of each small box: 13.25 Kilograms
Answer:
y=-1x+-3
Step-by-step explanation:
20% of x=6
20/100 of x=6
20x= 600
x=30
38% of 30=11.4
A.
To solve, you need to get the variable by itself.
Order of operations:
Square root both sides.
(x-5)= plus/minus root 3, as 3 is not a perfect square.
Now you need to add 5 to both sides to get it to disappear on the side with the x.
x=root3 +or - 5, which can be rearranged so that 5 is the first term.
4(4x)+(x)
= 16x+x
Combine like terms
16x+x
(16x+x)
= 17x
x=17
I hope that's help ! Good night .
