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

6x-3=3x+12<br>x= <br>What is the value of x in this equation​
goldenfox [79]

Answer:

x = 5

Step-by-step explanation:

6x - 3 = 3x + 12

-3x       -3x

_____________

3x - 3 = 12

    +3    +3

_____________

3x = 15

15 divided by 3 = 5

x = 5

You can double check this by replacing x with (5)

If it is right both sides should equal the same

6(5) - 3 = 3(5) + 12

30 - 3 = 15 + 12

27 = 27

This would prove that x = 5

True [87]

Answer:

More

Step-by-step explanation:

A percentage of some thing is usally less than the original cost, so we know it can't be more than 105. 75% of 105 dollars is $78.75 which is 3 dollars and 75 cents more than 75 dollars, so the answer would be more.

105 x .75 is 78.75
