6000\times 400=25000R\times 4
Multiply both sides by 400.
2400000=25000R\times 4
Multiply 6000 and 400 to get 2400000.
2400000=100000R
Multiply 25000 and 4 to get 100000.
100000R=2400000
Swap sides so that all variable terms are on the left hand side.
R=\frac{2400000}{100000}
Divide both sides by 100000.
R=24
Divide 2400000 by 100000 to get 24.
