7k-6\left(-7k+6\right)=-144-136
Multiply both sides of the equation by 4.
7k+42k-36=-144-136
Use the distributive property to multiply -6 by -7k+6.
49k-36=-144-136
Combine 7k and 42k to get 49k.
49k-36=-280
Subtract 136 from -144 to get -280.
49k=-280+36
Add 36 to both sides.
49k=-244
Add -280 and 36 to get -244.
k=\frac{-244}{49}
Divide both sides by 49.
k=-\frac{244}{49}
Fraction \frac{-244}{49} can be rewritten as -\frac{244}{49} by extracting the negative sign.
