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 $\frac{-2y}{-2}=\frac{-4}{-2}$ Divide each side by -2 y=2 Simplify

The solution is y=2
