Determine the density of the wood
First, we calculate the volume of the wood.
Substitute values for Length, Width and Height
The density is:
<em> --- approximated</em>
The solution of the equations is (-2, -1)
<h3>System of equation:</h3>
2x - 3y = -1
11x - 9y = -13
Using elimination method let multiply the first equation by -3.
Therefore,
-6x + 9y = 3
11x - 9y = -13
5x = -10
x = -10 / 5
x = -2
let's find y as follows;
2(-2) - 3y = -1
-4 - 3y = -1
-3y = -1 + 4
-3y = 3
y = 3 / -3
y = -1

Answer:
7 is x
Step-by-step explanation:
1) Divide both sides by 5 to give
4=-3+x
x=4+3
x=7
2) Multiply 5 with the RHS (Right Hand Side) to give
20=-15+5x
20+15=5x
35=5x
x=7
