I need to understand the rules of basic algebra. I understand the answer, I need to understand why it is the answer. x+23=2x+45
23=x+45. why does the 2x become...
the "x" is a multiplication sign not a variable
Need to simplify this equation and solve for 'a'
Would love it if absolute detail is giving on how to solve the question
i need to know this answer to the equation!
rewrite in standard form 2x^2+4x-1
How would you graph this and what would the plots be? Thanks!
x + 4y < 2
What would be the graphing plots to?:
I know one side should be shaded but not sure if the line is solid or dotted. Thank you!
rewrite in standard form -2x^2+3x+7
I'm not sure how to answer this problem so any help on how to solve this problem would be appreciated. Thanks!
Use addition or substitution to find the value of y for this set of equations. top line 2x - 3y = -15 bottom line x = 4y
I need to know the answer with the steps
My problem is that when we have a - sign like hust above does it count to a 1 which is minus or what. I really dont understand.Please give the answer like right now.
need hlp on how to solve question
