The answer is C. x=4
Explanation) 49 - 7 (4) = 21
7 (4) = 28
49 - 28 = 21
Answer:
12
Step-by-step explanation:
4x + 5y = 3 ................ (i)
kx + 15y = 9................(ii)
Dividing eqn (ii) by 3, we get,
k/3 x + 5y = 3.............(iii)
Subtracting eqn (iii) by eqn (i), we get,
-4x - k/3 x = 0
or, -(4 - k/3 )x = 0
or, 4 - k/3 = 0/x
or, 4 - k/3 = 0
or, 4 = k/3
or, k = 4*3
:. k = 12 (Ans)
Answer:
just add 386+165 which equals 551
Step-by-step explanation:
= -(14w + 8) + 8 = 3
= -14w - 8 + 8 = 3
= -14w = 3
w = -3/14
In short, Your Answer would be -3/14
Hope this helps!
