Answer:
x=15
Step-by-step explanation:
If x is 3 and y is 21, then that means that y is 7 times the value of x (21/3=7), or y=7x.
If y is 105, then 105=7x
105=7x
105/7=x
15=x
When ur variables cancel and ur left with a true statement...equal statements, such as 0 = 0 or 6 = 6, then u will have infinite solutions. So the answer to this is infinite solutions.
** now if u were left with 0 = 3 or 2 = -2....then there would be no solutions.
if u ended up with x = 7 or y = 5....a variable equal to a number, then there is 1 solution
Answer:
