Solve for U, R, I
U=127
R=10
I = \frac{127}{10} = 12\frac{7}{10} = 12.7

127=10I
Consider the first equation. Insert the known values of variables into the equation.
\frac{127}{10}=I
Divide both sides by 10.
I=\frac{127}{10}
Swap sides so that all variable terms are on the left hand side.
U=127 R=10 I=\frac{127}{10}
The system is now solved.
