420=340t-5t
Multiply both sides of the equation by 2.
420=335t
Combine 340t and -5t to get 335t.
335t=420
Swap sides so that all variable terms are on the left hand side.
t=\frac{420}{335}
Divide both sides by 335.
t=\frac{84}{67}
Reduce the fraction \frac{420}{335} to lowest terms by extracting and canceling out 5.
