Question

In the equation 8 + 2k = 4k + 4, use substitution to find the value of k.

Answer 1

k = 2

Explanation:

8 + 2k = 4k + 4

-2k -2k

8 = 2k + 4

-4 -4

4 = 2k

divide both sides by 2

2 = k

k = 2

Hope this Helps

Answer 2

k=2

Explanation:

8+2k=4k+4

Step 1: Simplify both sides of the equation.

2k+8=4k+4

Step 2: Subtract 4k from both sides.

2k+8−4k=4k+4−4k

−2k+8=4

Step 3: Subtract 8 from both sides.

−2k+8−8=4−8

−2k=−4

Step 4: Divide both sides by -2.

−2k

−2

=

−4

−2

k=2
