X = -4
y = 0
8x-12y+32 = 24
your answer to that division problem is 35.9
Answer: 16x -10
Step-by-step explanation:
2x + 14x = 16x
-4 - 6 = -10
Answer:
C. No solution
Step-by-step explanation:
System of Equations:
A) 
B) 
Simplifying and rearranging equation A.
Dividing each term by 3 (common factor for each term) in equation A.
Subtracting both sides by 
Adding 7 both sides.
Adding the above equation to equation B.
+
We have 
which is not true.
Hence the system has no solution. (Answer)
Answer:
The dimensions of the rectangle are two unknowns: The length "l" and the width "w"
The perimeter of a rectangle is found as P = 2*l + 2*w
We also know that the length is 5cm more than twice the width. l = 2*w + 5
These two equations gives us a system of linear equations.
P = 2*l + 2*w
l = 2*w + 5
We can use substitution to replace the "l" in the first equation with 2*w + 5
P = 2*(2*w + 5) + 2*w
P = 4*w + 10 + 2*w
P = 6*w + 10
We know that P = 34cm
34 = 6*w + 10
Subtract 10 from both sides
24 = 6 * w
Divide both sides by 6
4 = w
Now that we know the width, we can find the length by substituting 4 for "w" in the second equation.
l = 2*4 + 5
l = 8 + 5
l = 13
The dimensions of the rectangle is 13cm x 4cm
