=> 12 = 2x
=> x = 12/2
=> x = 6 (Ans)
Answer:
x=4 and y=5
Step-by-step explanation:
The given system of equations are
The matrix form is
Let as assume
then,
We know that,
Therefore, the value of x is 4 and value of y is 5.
Answer:
Step-by-step explanation:
I just finished this homework so
u have
-2 -8 -18 -32 -50
-2 to -8=-6
-8 to -18=-10
-18 to -32=-14
-32 to -50=-18 now the gaps are going by 4 so it will be n^2-4
