Answer :
Answer:
4.6
Step-by-step explanation:
so if you substitute the x for -3 you get -21+6y=7, to make it easier you plus the 21 on either side to get rid of it. so you now have 6y=28, to find y you divide by 6 on both sides so you get y=4.6
Answer:
Given x = -3
7x + 6y = 7
Step-by-step explanation:
7 * (-3) + 6y = 7
-21 + 6y = 7
6y = 7 + 21
6y = 28
y = 28/6
therefore y = 14/3.
