Question

y = 5 – x, solve for x

y = x + b, solve for x

y = a – x, solve for x

Answer 1

\[y = 5 – x\] add \(x\) to both sides and get
\[x+y=5\] then subtract \(y\) and get \(x=5-y\)

Answer 2

method 2)
\[y=5-x\] subtract \(5\) and get
\[y-5=-x\] then change the signs of both sides and get
\[5-y=x\]

Answer 3

\[y = x + b\], solve for x
subtract \(b\) from both sides
what do you get?

Answer 4

y = 5 – x
+x +x
--- ----
y + x = 5
-y -y
--- ----
x = 5 - y

Answer 5

@Ladyliz73 did you solve \(y=x+b\) for \(x\) ?

Answer 6

x=b-y Not sure i understand still...

Answer 7

y = x + b
y - b = x + b - b
y - b = x

that's hw you get x = y - b. The way you've written it is wrong because you're multiplying a -1 to the equation to somehow make the y negative. .
