2\left(-\frac{2\times 2+1}{2}\right)k=-\left(3\times 2+1\right)
Multiply both sides of the equation by 2.
2\left(-\frac{4+1}{2}\right)k=-\left(3\times 2+1\right)
Multiply 2 and 2 to get 4.
2\left(-\frac{5}{2}\right)k=-\left(3\times 2+1\right)
Add 4 and 1 to get 5.
-5k=-\left(3\times 2+1\right)
Cancel out 2 and 2.
-5k=-\left(6+1\right)
Multiply 3 and 2 to get 6.
-5k=-7
Add 6 and 1 to get 7.
k=\frac{-7}{-5}
Divide both sides by -5.
k=\frac{7}{5}
Fraction \frac{-7}{-5} can be simplified to \frac{7}{5} by removing the negative sign from both the numerator and the denominator.
