Simplifying 2x + 4y = 8 Solving 2x + 4y = 8 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4y' to each side of the equation. 2x + 4y + -4y = 8 + -4y Combine like terms: 4y + -4y = 0 2x + 0 = 8 + -4y 2x = 8 + -4y Divide each side by '2'. x = 4 + -2y Simplifying x = 4 + -2y
I was told we were supposed to have it y= not x=... But is that does seem right
hint: solve for "y"
@mathwiz916 please read the question before answering.
ooops sorry lol
@tb1 slope intercept format y = m x + b
whatever you do to one side of the equation also do to the other to keep the balance
when solving for any variable in any equation, gather all the terms with that variable to one side and simplify then divide each side by the coefficient of the variable
|dw:1444432394271:dw| i'm not sure, its been a while, are u trying to get y by itself?
make 4y the subject means leave that on one side rest on the other then divide each side by 4
@ecfhuuewchfr then rearrange to put in the correct format
@tbl is everything clear now?
I think I do but can you explain one more time just to be sure?
And also possibly help me with another question?
