M=-1
4m+2(m+1)=9m +5
4m+2m+2=9m+5
6m+2=9m+5
6m+2-6m= 9m+5-6m
2-5=3m+5-5
-3/3=3m/3
m=-1
Step-by-step explanation:



The new matrix obtained from a given matrix by interchanging it's rows and columns is called the transposition of matrix. It is denoted by
. Again , Interchange it's rows and columns in order to find ' A '.

Now , LEFT HAND SIDE ( L.H.S )

Here, I refers to identity matrix. A diagonal matrix in which all the elements of leading diagonal are 1 ( unit ) is called unit or identity matrix.

Answer:
P(w) = 9w+5
Step-by-step explanation:
You see every week there is an increase of 9, and it starts at 5. That's all you need to know for a linear equation.
If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:
equation a: 2c = d - 8 /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5
<span>The correct result would </span>be: <span>multiply equation a by −3.</span>
