8I+40I-224=0
Use the distributive property to multiply 40 by I-5.6.
48I-224=0
Combine 8I and 40I to get 48I.
48I=224
Add 224 to both sides. Anything plus zero gives itself.
I=\frac{224}{48}
Divide both sides by 48.
I=\frac{14}{3}
Reduce the fraction \frac{224}{48} to lowest terms by extracting and canceling out 16.
