How do you do the problem 4k+7(-4-2k)=-2(k-2)
Please help me I keep trying and can't get the right answer thanks-steph
if you're trying to find the value of k which satisfies the equation, just unwind the expressions.
4k - 28 - 14k = -2k + 4
Now combine terms:
-10k - 28 = -2k + 4
Now move all the "k" stuff to one side and the numbers to the other:
-8k+2k = 4 + 28
Combine terms again:
-8k = 32
Divide by the coefficient of k:
k = -4
Thank you so much
