Answer: all real numbers
Step-by-step explanation:
the domain for any function is always, all real numbers or in other words, negative infinity to positive infinity.
Answer: x = (cd + by) / a
Working out:
(ax - by) / c = d
1)Multiply by c on both sides to get:
ax - by = cd
2) Add by on both sides to get:
ax = cd + by
3) divide by a on both sides to get:
x = (cd + by) / a
The answer is 0.444 repeating.
