To answer this question, we need to pose the problem algebraically as follows:
1. The sum of two numbers is -29:
2. The difference of the two numbers is -13:
Then, we have a linear system of equations, and we can solve it by elimination, substitution, as the most suitable for this case. Then, we have that we can sum both equations and we get:
Thus, we have that the value for x = -21. We can use the first equation to substitute this value of x to find the value for y. Then, we have:
Therefore, the two numbers are -21 and -8.
We can check this as follows:
1. -21 + (-8)= -21 -8 = -29
2.-21 -(-8) = -21 + 8 = -13
8m(4+7p). (The greatest common factor is 8.).

Answer:
£43
Step-by-step explanation:
925×2/100
=£ 18.5
2.4 years =18.5×2.4
=£43
Here are the two equations for this problem:
Let length = L
Let width = W
Equation No. 1 -
L = 2W
Equation No. 2 -
2L + 2W = 36
First simply substitute the value of ( L ) from the first equation into the second equation to solve for ( W ) as displayed below:
Equation No. 2 -
2L + 2W = 36
2 ( 2W ) + 2W = 36
4W + 2W = 36
6W = 36
W = 36 / 6
W = 6
Now, we substitute the value of ( W ) from the second equation into the first equation to solve for ( L ) as displayed below:
Equation No. 1 -
L = 2W
L = 2 ( 6 )
L = 12
Therefore, L = 2W and 2L + 2W = 36 are the correct equations for this problem.
