Use the distributive property on the left hand side.
Now move all unknown terms to the left hand side, known terms on the right hand side using multiplicative inverse and additive inverse as needed.
Subtract from both sides.
Subtract from both sides.
Use the distributive property on the left hand side.
Multiply both sides by the multiplicative inverse of .

a(x+2)=bx+a can't be solved for numeric values since there are 3 variables (x,a,and b ) and only one equation.
The general rule is one equation for each variable so that if you have three unknowns you need three equations.

You aren't very clear about what you want. Contrary to my normal modus operandi, I'm going to make the assumption that you want to solve for 
in terms of 
and 
.
Distribute the in the LHS.
Add 
to both sides
Add 
to both sides
Factor out of the LHS expression
x\ =\ -a)
Multiply both sides by 
Going into the ninth grade is the time to stop taking the "cookbook" approach to mathematics. Learn the PRECISE definitions of things and use them to say exactly what you mean.
