Answer:
42 x - 24 x n - i = 0
Step-by-step explanation:
Expand the following:
6 x (7 - 4 n) = i
6 x (7 - 4 n) = 6 x×7 + 6 x (-4 n):
6×7 x - 4×6 x n = i
6×7 = 42:
42 x - 4×6 x n = i
6 (-4) = -24:
42 x + -24 x n = i
Subtract i from both sides of 42 x - 24 x n = i:
42 x - 24 x n - i = i - i
-i + i = 0:
Answer: 42 x - 24 x n - i = 0
