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

Solve for y -3x plus 6y equals 12?
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
How do you turn 3x-6y equals 12 in slope intercept form?
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
What is 3x plus 6y plus 6x?
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
How many values of x and y satisfy the equations 2x plus 6y equals 12 and 3x plus 9y equals 18?
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.
What is the slope-intercept of 6y - 3x equals 18?
If: 6y-3x = 18 Then: y = 0.5x+3 which is in slope-intercept form
Solve for y -3x plus 6y equals 12?
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
What is 3x plus 6y equals 12 in slope-intercept form?
3x + 6y = 12 Rearranging terms: 6y = -3x + 12 Divide through by 6: y = -1/2*x + 2
What is the ordered pair of 3x plus 6y equals 36 3x-6y equals 0?
3x + 6y = 363x - 6y = 0 add both equations6x = 36x = 63x - 6y = 03(6) - 6y = 018 - 6y = 018 = 6y3 = yThe solution point is (6, 3).
How do you turn 3x-6y equals 12 in slope intercept form?
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
Is 3x-6y equals 12 a parallel line?
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
What is 3x plus 6y plus 6x?
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
How do you get y by itself in the equation 3x-6y equals 9?
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
What is the y-intercept of 3x-6y equals 72?
[ y = -12 ] is.
The greatest monomail factor of 3x-6y plus 12?
3
5x2 y equals 3x-6y as a function?
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
What is 3x-6y equals 9 in slope-intercept form?
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
How many solutions does this system have x-2y equals 6 and 3x-6y equals 18?
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
