Solve `8=5k+3` .

In orderto solve for k we must isolate the variable.  Therefore, we must "undo" +3 first, by subtracting 3 from both sides.

`8 - 3 = 5k + 3 - 3`

`5 = 5k + 0`

`5 = 5k`

Now we must divide both sides by 5 to undo the multiplication of 5 to k.

`5/5 = (5k) /5`

`1 = k`

Therefore, the  solution to `8 = 5k + 3` is `k = 1` .

Check---------------

Substitute 1 for k into original equation.

`8 = 5(1) + 3`

`8 = 5 + 3`

`8=8`

Since this is true, the solution checks.

`8=5k+3` Subtract 3 from both sides.

`5=5k` Divide both sides by 5.

`k=1` <--Your solution

What is the solution to 8=5k+3

Well this is a simple algebra problem where you would have to find k instead of x

The way to solve this problem is to put the variable on one side and the numbers on the other side

8-3=5x

By simplifying you would get 

5=5x

Then divide and x=1

QUESTION:-

What is the solution to 8=5k+3?

SOLUTION:-

8 = 5k + 3

Subtract 3 from both sides;

8 - 3 = 5k + 3 - 3

5 = 5k 

Divide by 5 both sides or directly transfer 5 from LHS numerator to RHS denominator;

5 = 5k 

k = 5/5

k = 1

Hence the answer is 1. Hence Solved!

8 = 5k + 3

Just follow the order of operations, also isolate the variable k to find it's value,

8 = 5k + 3

8 - 3 = 5k + 3 - 3     Subtract 3 from both sides

5 = 5k

5/5 = 5k/5               Divide both sides by 5

1 = k

k = 1 Answer.

8=5k+3

so first subtract 3 from both sides

5=5k

divide both sides by 5

1=k and that's your answer

8 = 5k + 3

In order to solve this equation,  first subtract 3 on both sides in order to get " k " alone

By subtracting, your equation should look like

5 = 5k now divide both sides by 5

By dividing your equation should look like

1 = k which is your answer

 8=5k+3   we want to have all the x's or unknown variables on one side, so lets try to remove the 3 by subtracting 3 from both sides

8-3=5k

5=5k

divide by 5 to get the k alone by itself

k=1

voila! :)

8=5k+3

5= 5k  subtract 3 from each side

k=1 divide both sides by 5

To solve equations for a single variable, think of it as undoing what has already been done so that you can isolate the variable. 

8=5k+3

In this case, the variable is having 3 added to it so we can subtract 3 to get : 

5 = 5k 

Then, we can undo the multiplication by dividing both sides by 5 : 

1 = k

8=5k+3

first subtrack 3 from both sides

8-3=5k

5=5k

then divide 5 by both sides

5/5=k

k=1

and k=1 is the solution
