Dealing with fractions and equations we need to cross multiply.
-2k/7=36/1
The left numerator (-2k) times right denominator (1) equals the right numerator (36) times the left denominator (7). Thus we have:
-2k*1=36*7
-2k=252
k=252/-2
k=-126 ans.
Proof:
-2*-126/7=36
252/7=36
36=36

-2k%2F7=36 multiply both sides by 7
:
cross%287%29%28-2k%29%2Fcross%287%29=36%287%29
:
-2k=252 your left with
:
cross%28-2%29k%2Fcross%28-2%29=252%2F-2 dividing both sides by -2
:
highlight%28k=-126%29 252 divided by -2=126
