Option A is correct.
Step-by-step explanation:
We need to identify which statement is true in matrix addition.
In matrix addition we just add the corresponding elements.
In the options given only Option A is correct i.e, (n+4)-7 = 18
All other options have error in them.
In Option B there should be -12 instead of +12
In Option C there should be -11 instead of 11
In Option D we are not adding corresponding entries.
So, Option A is correct.

Answer:
C. T = 4n+6/2
Step-by-step explanation:
4n = 2(T-3)
or, 4n = 2T-6
or, 4n + 6 = 2T
or, 4n + 6 / 2 = T
or, T = 4n + 6 / 2
Answer:
A. One line
Step-by-step explanation:
Let rearrange the system of equations into explicit forms:
The second equation is identical to the first one, which means that there is just one line.
Answer:
≤ 14
Step-by-step explanation:
2 * x - 5 ≤ 18
divide 2 from both sides.
x - 5 ≤ 9
the answer is less than or equal to 14
