ok well the answer i got to was y= -4.5, i came to that by subtsituting in 5 for the x value and solving for y i assumed everything was adding together since you didnt say otherwise. ill show my work now 3(5)+6y+12 =15+6y+12 =27+6y -27/6=6y/6 y=-4.5
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
3x-6y=12; subtract 12 & add 6y to both sides 3x-12=6y; divide by 6 (1/2)x-2=y; re-write y=(1/2)x-2 slope intercept form
Well, darling, 3x plus 6y plus 6x simplifies to 9x + 6y. That's all there is to it, sugar. Math doesn't have to be complicated, just like your love life!
2X + 6Y = 12 3X + 9Y = 18 try elimination - 3(2X + 6Y = 12) 2(3X + 9Y = 18) - 6X - 18Y = - 36 6X + 18Y = 36 ================= I will say this system is dependent and an infinite number of solutions can be found.
If: 6y-3x = 18 Then: y = 0.5x+3 which is in slope-intercept form
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
3x + 6y = 12 Rearranging terms: 6y = -3x + 12 Divide through by 6: y = -1/2*x + 2
3x + 6y = 363x - 6y = 0 add both equations6x = 36x = 63x - 6y = 03(6) - 6y = 018 - 6y = 018 = 6y3 = yThe solution point is (6, 3).
3x-6y=12; subtract 12 & add 6y to both sides 3x-12=6y; divide by 6 (1/2)x-2=y; re-write y=(1/2)x-2 slope intercept form
It is a straight line. standard form is y = mx + b where m = slope 3x - 6y = 12 6y = 3x -12 y = .5x -2 any other line with slope = 0.5 would be parallel to it
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6

[ y = -12 ] is.
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
3x - 6y = 9Subtract 3x from each side:-6y = -3x + 9Multiply each side by -1 :6y = 3x - 9Divide each side by 6:y = 0.5x - 1.5
6y-3x-9(1-1)=6y-3x-9(0)=6y-3x-0=6y-3xOnly like terms can be simplified. A like term has the same variables, X and Y are different variables. 6y-3x cannot be simplified because they are not like terms.
Let's see. Looks like easy substitution here. X - 2Y = 6 3X - 6Y = 18 express one variable in term of another with top equation X - 2Y = 6 X = 2Y + 6 insert into bottom equation 3(2Y + 6) - 6Y = 18 6Y + 18 - 6Y = 18 ---------------------------------admits of no solution here, try elimination - 3(X - 2Y = 6) 3X - 6Y = 18 - 3X + 6Y = - 18 3X - 6Y = 18 This system either admits of no solution, or an infinite number of solutions, but my systems work is rusty, so I do not remember the terms
