##### Enter Equation or Inequality

Solve the following equation

2y-5=3y-15

Solve for y

2y - 5 = 3y - 15

##### Group variables

Group our variables 2y and 3y
subtract 3y from both sides

2y - 5 - 3y = 3y - 15 - 3y

-y - 5 = -15

##### Group constants

Group our constants -5 and -15.

-y - 5 + 5 = -15 + 5

-y = -10

 -1y -1
 =
 -10 -1

y = 10

y = 10
