Answer:
n = 13/7
Explanation:
Solve the equation
Step 1: Use distributive property to multiply out the terms with parenthesis
(1/2)(2n) + (1/2)(4) + 6 = -9 + 4(2n) + 4(1)
n + 2 + 6 = 9 + 8n + 4
Step 2: combine like terms...
n + 8 = 8n - 5
Step 3: Get all "n's" to one side, and all constants on the other and solve
13 = 7n (subtract n from both sides and add 5 to both sides)
13/7 = n (divide both side by 7)
