Question 885016: So i have been going over the linear models for over a month now.I am in eighth grade going on to the ninth.I will be taking algebra 2 but im having a hard time understanding it. I'm extremely confused on the actual problems. how do you go about solving them.for example : a(x+2)=bx+a
thanks so much

Use the distributive property on the left hand side.
a%28x%2B2%29=bx%2Ba
ax%2B2a=bx%2Ba
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 bx from both sides.
ax-bx%2B2a=bx-bx%2Ba
ax-bx%2B2a=a
Subtract 2a from both sides.
ax-bx%2B2a-2a=a-2a
ax-bx=-a
Use the distributive property on the left hand side.
x%28a-b%29=-a
Multiply both sides by the multiplicative inverse of %28a-b%29.
x%28a-b%29%2A%281%2F%28a-b%29%29=-a%2F%28a-b%29
highlight%28x=-a%2F%28a-b%29%29

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



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.
