+8261 There are many ways to solve this problem. I will give on solution.
Solution: 3x+y=-4 = 3*1+-7
= 3+-7
= -4
That is my sloution for this math question. Hope it helps!
+11912 how and where did u find that-7 DragonSlayer!can u pls explain this to me in more detail of how u sloved this!
+128460 3x + y = –4 ...Rearranging this equation, we have
y = -3x - 4 ......this is the equation of a line that has infinite answers....here's a graph:
+128460 DS and rosala......saying that the equation can't be "solved" isn't exactly correct......it just has infinite solutions......!!!!! (not just one solution)......there are many "x's" and "y's" which make the equation "true"......
+11912 Hmmm!thanks for the correction CPhill!I'll take care next time!
Thumbs up for your graph!
+676 To Solve this equation we will need to isolate either one of the variables.
For the fun of it, lets isolate the X variable.
Lets write the equation below:
$$3x+y=-4$$
Now lets us isolate the X
Essentially, this is the answer, however you may with substitute it into the equation.
$$y=-4-3x$$
Now let us substitute:
$$3x+(-4)-3x=-4$$
+8261 Okay. I will, rosala.
Solution: 3x+y=-4 = 3*1+-7
= 3+-7
= -4
Solution (Same as above but in words): First, you write out the math problem. Then, you subsitute x and y. BUT you HAVE to subsitute x first. So, if x=1, multiply 3 by 1. After that, because you have 3 and y, so to make -4, turn y into -7. Finally, you add positive 3 and negative 7 which makes -4. That is your answer.
+8261 Yes. There are an infinite of solutions to solve this problem. I wrote the second easiest way to solve it.
+8261 CPhill, I know that there are many solutions to the problem. That's what I wrote.
