Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
I'm taking an introductory algerbra course and the following equation is confusing me.
Isolate/Solve for x:
z= (-3) / (2x-1)
My first instinct is to multiple both sides by 2x-1 to eliminate the fraction.
But I'm also wondering if I'd be better to multiple by 1/-3?
So when I try to multiply z by 2x=1, I don't know what to do and feel like I'm approaching this incorrectly.
Your approach of starting with multiplied both sides by 2x - 1 is correct. Here are the next steps.
