How do you solve #\frac { k } { 6} + 8= 7#?

Answer 1

Avery Alexander

#k = -6#

Subtract the #8# from both sides:

#k/6 +8 - 8 = 7 - 8# #k/6 = -1#

Multiple both sides of the equation by #6#: #(6k)/6 = -1(6)# #k = -6#

To solve the equation, first, isolate ( k ) by subtracting 8 from both sides:

[ \frac { k } { 6} + 8 - 8 = 7 - 8 ]

[ \frac { k } { 6} = -1 ]

Next, multiply both sides by 6 to solve for ( k ):

[ 6 \times \frac { k } { 6} = -1 \times 6 ]

[ k = -6 ]

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.
