-4k + 10 - k + 2 = 2k + 4k + 18
Combine all the 'k' terms on the left side:
-5k + 10 + 2 = 2k + 4k + 18
Combine all the 'k' terms on the right side:
-5k + 10 + 2 = 6k + 18
Combine the numerical terms on the left side:
-5k + 12 = 6k + 18
Add 5k to each side:
12 = 11k + 18
Subtract 18 from each side:
-6 = 11k
Divide each side by 11:
k = -6/11

y= -9
The value 6.5 does.
That equation has no solution. There is no possible number that's equal to 18 more than itself.
72 but there is such a thing as a CALCULATOR
one solution to that is 3*6 + 2*0=18 but, if you need both numbers then 3*2 + 2*3
