I hope I help with this information also did the math and got confused and limited to those two answers
If you find your common factors it would be 14m + 2m
Answer:
Garden Table: $750
Bench: $250
Step-by-step explanation:
Use the system of equation. Let "garden table" = x, and "bench" = y.
x + y = 1000
x = 3y
Solve for each variable. Note that x = 3y. Plug in 3y for x in the first equation:
x + y = 1000
(3y) + y = 1000
Simplify. Combine like terms:
4y = 1000
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 4 from both sides:
(4y)/4 = (1000)/4
y = 1000/4
y = 250
A bench = $250.
Plug in $250 for y in one of the equations:
x = 3(y)
x = 3(250)
x = 750
A garden table = $750
The cost of the bench is $250.

Posted to your other question as well:
So we have:
A)
B)
C)
D)
We need to try x = –6 in each equation until we find a solution that makes both sides of the equation equal.
For A, this gives an undefined result. Logarithms are only defined for bases that are positive real numbers not equal to 1.
For B, this again gives an undefined result. The logarithm of a number is only defined when that number is a positive real number. It would be –21, which is undefined.
For C, we have a defined operation, but
.
Finally, for D, we have
This is true.
