How do you solve #\frac { 8n - ( - 2) } { 7} = 6#?

Answer 1

Kennedy Adams

#8n=40#

#(8n-(-2))/(7)=6#; mulitply BOTH sides by #7#,

#(8n-(-2))/7xx7=6xx7#,

#(8n-(-2))=42#, we remove the brackets from the #"left hand side:"#

#8n+2=42#, SUBTRACT #2# from each side:

#8n+2-2=42-2#,

#8n=40#

#n=40/8=??????#

To solve the equation (\frac{8n - (-2)}{7} = 6), follow these steps:

First, simplify the expression inside the parentheses: (-(-2) = 2).
Rewrite the equation: (\frac{8n + 2}{7} = 6).
Multiply both sides of the equation by (7) to eliminate the fraction: (7 \times \frac{8n + 2}{7} = 6 \times 7).
Simplify both sides: (8n + 2 = 42).
Subtract (2) from both sides to isolate (8n): (8n = 42 - 2).
Simplify: (8n = 40).
Divide both sides by (8) to solve for (n): (n = \frac{40}{8}).
Simplify: (n = 5).

Therefore, the solution to the equation is (n = 5).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
