How do you solve #k-25=30#?

Answer 1

Kennedy Adams

#k = 55#

Just collect like terms and you're good to go..

#k - 25 = 30#

#k = 30 + 25#

#k = 55#

or..

Using Distributive method..

#k - 25 = 30#

Since our major aim is to get the value of #k#..

Add #color(red)(25)# to both sides..

#k - 25 + color(red)(25) = 30 + color(red)(25)#

#k cancel(- 25 + 25) = 30 + 25#

#k + 0 = 30 + 25#

#k = 30 + 25#

#k = 55#

To solve the equation ( k - 25 = 30 ), you add 25 to both sides of the equation to isolate the variable ( k ). The solution is ( k = 55 ).

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.
