Answer:
n=3 5/7
Explanation:
8(n+7) Multiply each term in the parenthesis by 8
8n + 8 x 7
8n + 56
4 - 6n = 8n + 56
move variable to the left by adding its opposite to both sides
-6n - 8n + 4 = 8n - 8n +56
eliminate the opposites
-6n - 8n + 4 = 56
collect like terms by calculating the sum or difference of their coefficients
-6n - 8n
(-6 - 8)n
calculate the difference
-14n
divide both sides of the equation by -14
-14n / (-14) = 52 / (-14)
n = 52 / (-14)
n = -52/14
n= -26/7
alternative form of writing the answer is
n= -3 5/7 or n= 3.71429
