25k+20k-10-32=0
Use the distributive property to multiply 2k-1 by 10.
45k-10-32=0
Combine 25k and 20k to get 45k.
45k-42=0
Subtract 32 from -10 to get -42.
45k=42
Add 42 to both sides. Anything plus zero gives itself.
k=\frac{42}{45}
Divide both sides by 45.
k=\frac{14}{15}
Reduce the fraction \frac{42}{45} to lowest terms by extracting and canceling out 3.
