how can I isolate y in algebra?? I would like to get a simple as possible instructions for this please and?

Question

thank you.

Or isolate x variable

Answer 1

You need to reverse anything done to y by doing the same thing to each side of the equation, going in backwards order of operations. For example in 3y-4=x

you would start by adding 4 to each side of the equation, where on the left, it would cancel out the "-4." On the right it would be added to x

Then divide both sides by 3 with the same result

Answer 2

Use all your knowledge to find the inverse of the coefficient of x
e.g. 3+x=7; transpose 3 so x can be isolated, having the inverse of three which is "-3"
e.g. 4x=16; by looking at it, the operation used in these equation is multiplication, so use the multiplicative inverse which is division, divide both sides by four to isolate x
e.g. x^2 (x squared)=81; use the inverse, which is nth root, in this case use the square root property to isolate x.

Answer 3

Do the same thing to both sides of the equation.

If it's y+3 = 10, you'd subtract 3 from both sides.
If it's y-3=10, you'd add 3 to both sides
if it's 3y=10, you'd divide both sides by 3
if it's y/3=10, you'd multiply both sides by 3

You may have to do more than one of these to isolate a term.

Now you know the answer you "why ask y?"

Answer 4

Add or subtract all the values to one side so your left with Y..if there is a coefficent...divide both sides by that value so you are left with y..
ex. 3y + 2= 6
3y=6-2
3y=4
y=4/3

Answer 5

-x+y=4

Add x from both sides:
y=x+4

That's an example on how to isolate the y in algebra.
