Answer:
K= -2
Explanation:
20-6+4*k-(2-2*k)=0
Pull out like factors
12 + 6k = 6 • (k + 2)
Solve: 6 = 0 which ends that this equation has no solution because a non zero constant never equals zero
Solve: K+2 = 0
now substract 2 from both sides of the equation: K= -2
Hope I explained myself :/
Hope it helps :)
