Solve equations involving like terms

A common type of linear equation is one in which the variable terms are not combined into one term. In such cases, you can begin the solution combining like terms.

Solve 3y+8-5y=4

3y+8-5y=4

  Write original equation

3y-5y+8=4

  Group like terms

-2y+8=4

  Combine like terms

-2y+8-8=4-8

  Subtract 8 from each side

-2y=-4

  Combine like terms



  Divide each side by -2

y=2   Simplify

The solution is y=2
