What is 3x times 2y?
3x times 2y=3x2y. Without the measurements of x and y it is impossible to answer that math problem any further, so in the future, include the measurements of x and y,if any,in your question.

What are the solutions to the simultaneous equations of 3x plus 2y equals 5 and x plus 2y equals 7?
x = 7 - 2y 3x = 21 - 6y 21 - 6y + 2y = 5 21 - 4y = 5 21 - 16 = 5 4y = 16 y = 4 x + 8 = 7 x = -1 Check it. -3 + 8 = 5 -1 + 8 = 7 It checks.
What is 3x plus 6y plus 6x?
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
What type of linear system is 7x plus 2y equals 16 -21x-6y equals 24?
Do you mean 7x+2y = 16 and 21x-6y = 24? If so then it is simultaneous equation with the solution being: x = 12/7 and y = 2
Is 7x plus 2y equals 16 and -21x-6y equals 24 a no solution?
Multiplying the first equation by -3 gives -21x - 6y = -48 but the other equation gives 24 as the value of the same expression, so you are correct, there is no solution
What does y equal in this equation 8x plus 6y equals 16 4x-2y equals 8?
x = 2, and y = 0. Here's one way to solve:Multiply the second equation (both sides) by 3, then add the two equations:8x + 6y = 1612x - 6y = 24----------20x = 40 ----> x = 2, then substitute x=2 into one of the original equations:8*2 + 6y = 16 --> 6y = 0, and y=0. Check with the other equation: 4*2 - 2y = 8 ---> -2y = 0, and y = 0.
What is 6y - 8y?

2x plus 6y equals 24 and 5x - 2y equals 9?
(3, 3)
9y-3y plus 2y equals?
9y-3y=6y; 6y+2y=8y; so your answer is 8y
What is the order pair for 2x plus 6y equals 24 and 5x - 2y equals 9?
(3,3)
What is 6y equals 5y plus 2y?
6y equals 5y plus 2y can be simplified to 6y = 7y. To solve for y, subtract 7y from both sides of the equation, which gives 6y - 7y = 0. This simplifies to -y = 0, or y = 0.
How do you factor 8y3-16y2 plus 6y?
2y(2y - 1)(2y - 3)
How do you factor 8y3 -16y2 plus 6y?
2y(2y - 1)(2y - 3)
