Question

In the equation VT + V1 + 14 = 3V7 + 10, what is the value of j?

A. 2
B. 16
C. 4
D. 12

Answer 1

The value of j in the equation VT + V1 + 14 = 3V7 + 10 + j, where V= 7, V1 = 4, V7 = -9, T = 5 is 70. Option B is answer.

Explanation:

Substituting the given values in the equation, we get:

V(T) + V1 + 14 = 3V7 + 10 + j

7(5) + 4 + 14 = 3(-9) + 10 + j

35 + 18 = -27 + 10 + j

53 = j - 17

j = 53 + 17

j = 70

Therefore, the value of j when V=7, V1=4, V7=-9 and T=5 is 70. Option B is answer.
