3(k-3.4)=-3.5(k-5.1)
We move all terms to the left:
3(k-3.4)-(-3.5(k-5.1))=0
We multiply parentheses
3k-(-3.5(k-5.1))-10.2=0
We calculate terms in parentheses: -(-3.5(k-5.1)), so:We get rid of parentheses
-3.5(k-5.1)
We multiply parentheses
-3.5k+17.85
Back to the equation:
-(-3.5k+17.85)
3k+3.5k-17.85-10.2=0
We add all the numbers together, and all the variables
6.5k-28.05=0
We move all terms containing k to the left, all other terms to the right
6.5k=28.05
k=28.05/6.5
k=4+1/3.1707317073171
