##### Enter Equation or Inequality

Solve the following equation

30s-1560=180

Solve for s

30s - 1560 = 180

##### Group constants

Group our constants -1560 and 180.
add 1560 to both sides

30s - 1560 + 1560 = 180 + 1560

30s = 1740

##### Divide each side of the equation by 30

 30s 30
 =
 1740 30

s = 58

s = 58

s = 58
