-9+8k=7+4k(if there is no solution,type in ''no solution'') k= Answer

Shtirlitz [24]

Answer:

k = 4

Step-by-step explanation:

-9 +8k = 7+4k

Subtract 4k from each side

-9 + 4k = 7

Add 9 to each side

4k = 16

Divide by 4

k = 4

Plug in the value you got for k:

-9 + 8(4) ? 7 + 4(4)

-9 + 32 ? 7 + 16

23 ? 23

23 = 23
