Answer:
There are no variables, there is only a 1
Step-by-step explanation:
Answer:
y = -1, x = -2
Step-by-step explanation:
First, multiply the top equation by 2 to make 3x become 6x:
6x - 8y = -4
Second, multiply the bottom equation by 3 to make -2x become -6x:
9y - 6x = 3
Add the two equations together, and you get:
y = -1
Plug in y as -1 into the first or second equation:
3x - 4(-1) = -2
OR
3(-1) - 2x = 1
x = -2
Answer:
The width would be 86cm
Step-by-step explanation:
Perimeter is (Width*2) +(Length*2)
Length is 96, multiply by 2 : 96*2 = 192
Subtract this from the total perimeter (364-192 = 172)
Divide this by 2 to get 1 width value (172/2 = 86)
86 cm
There are two solutions.
.. (3, 2)
.. (0.2, -3.6)
