Please help me solve for x for this equation: .
:
Multiply both sides by (x+z) and you have:
y(x+z) = xa
:
Multiply what's inside the brackets by y
yx + yz = xa
:
Subtract yz from both sides:
yx = xa - yz
:
Subtract xa from both sides:
yx - xa = -yz
:
Factor out the x:
x(y-a) = -yz
:
Divide both sides by (y-a)
x =
:
You can get rid of the negative like this:
x =
:
x =
:
Could you follow this OK?

multiply both sides by (x+z)

expand y(x+z)

subtract yz from both sides
and xa from both sides

factor out x from the left side

divide both sides by (y-a)
answer
If you multiply the top and bottom of the right side
you get an alternate way to express answer:
also correct
