Answer:
Step-by-step explanation:
[1] 2x + y = -1
[2] x - 2y = -8 <------- given linear equations
Graphic Representation of the Equations : ----> given in attatchment
y + 2x = -1 -2y + x = -8 < ----- point where they connect is shown in graph
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = 2y - 8
// Plug this in for variable x in equation [1]
[1] 2•(2y-8) + y = -1
[1] 5y = 15
// Solve equation [1] for the variable y
[1] 5y = 15
[1] y = 3
// By now we know this much :
x = 2y-8
y = 3
// Use the y value to solve for x
x = 2(3)-8 = -2
Solution :
{x,y} = {-2,3}

What do you have to find?
do you just need to solve the problem with those numbers?
$30 because 12/6 = 2 so 15 x 2 = 30
The volume of the rectangular solid is: 11,960 units³.
<h3>How to Find the Volume of a Rectangular Solid?</h3>
The formula to find the volume of a rectangular solid is: (length)(width)(height).
Given the dimensions as:
- Length = 20 units
- Width = 23 units
- Height = 26 units
Volume = (20)(23)(26)
Volume of the rectangular solid = 11,960 units³.
