3n+4=-5
do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.
-5-4=-9
since 4-4=0, we can take 4 out of the equation. now you have:
3n=-9
now divide -9 by 3
-9/3=-3
n=-3
hope this helps :)
Answer: the length is 24m
The width is 6 m
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of the given rectangle is 60 meters. This means that
2(L + W) = 60
Dividing through by 2, it becomes
L + W = 60 /2
L + W = 30 - - - - - - - - - - - - - -1
The rectangular room is 4 times as long as it is wide. This means that
L = 4W
Substituting L = 4W into equation 1, it becomes
4W + W = 30
5W = 30
W = 30/5
W = 6
L = 4 × 6
L = 24
Answer:
No solution
Step-by-step explanation:
3x + 5 - x = 2(x-1)-4
2x + 5 = 2x - 2 - 4 Add the like terms. Distribute the 2.
2x = 2x - 6 - 5 Subtract 5, add like terms
2x = 2x - 11 Add like terms
0 ≠ -11 Subtract 2x to keep variables on one side
Since zero does not equal -11, there are no solutions
