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 x-x+23=2x-x+45 23=x+45. why does the 2x become...
the "x" is a multiplication sign not a variable
3(-X-4)=2X +3(X-5)
Need to simplify this equation and solve for 'a'
SOLVE X^2-10X+5=0
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?: -4x-5y>-20 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
what is 6 + 6 X 0 + 2
It's really important
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. thankyou
x^2-x+2x-2 hellllllllllllllllllllllllllllllllllllllllllllllppppppppppp
Complete the square
need hlp on how to solve question
