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+85y=4
3y+85y=4


Write original equation

3y5y+8=4


Group like terms

2y+8=4


Combine like terms

2y+88=48


Subtract 8 from each side

2y=4


Combine like terms



Divide each side by 2

y=2 

Simplify 
The solution is y=2
