What is 6x plus 3y plus 6y-2x?
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
Does the equation 2x plus 6y equals 35 have any whole-number solutions Why or why not?
no
2x plus 3y-5plus 3y-6 equals?
Collect like terms: 2x + 3y + 3y - 5 - 6 2x + 6y - 11
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.
How do you graph 5x-6y equals -30?
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
If 2x plus 1 equals y what does 12x plus 6 equals?
6y
X - 3y equals -3 and -2x plus 6y equals 12 solution?
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
4x plus 6y equals 14 -2x plus 2y equals -2?
(2, 1)
What is the y intercept of 2x plus 6y equals -24?
it is -4
Is 2x plus 3y equals 8 n 4x plus 6y equals 15 inconsistent?
yes
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24?
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
2x plus 6y equals 24 and 5x - 2y equals 9?
(3, 3)
What is 6x plus 3y plus 6y-2x?
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
Which type of lines are 4x plus 6y equals 12 and 2x plus 3y equals -6?
They are parallel lines.
What is the order pair for 2x plus 6y equals 24 and 5x - 2y equals 9?
(3,3)
Does the equation 2x plus 6y equals 35 have any whole-number solutions Why or why not?
no
In 2x plus 6y equals 32 what is x?
2x plus 6y equals 32 32 divided by 6= 5 R2 5+2= 7x6= 42-5=37-2=35 so X=5
