Answer :
The answer is y=5 when x=0. 5 times 0 is 0 which means the equation would be 3y=15. 3 times 5 is equal to 15 therefore y=5.
y= 5 because if you substitute 0 into x, you'll get
5 times 0 + 3y= 15
5 times 0= 0
Then, get 15-0=15
Finally, 15 divided by 3 will equal 5.
5 times 0 + 3y= 15
5 times 0= 0
Then, get 15-0=15
Finally, 15 divided by 3 will equal 5.
