To work out the expression (2x + 6y), you simply identify the values of (x) and (y) if they are given. Then, multiply (x) by 2 and (y) by 6. Finally, add the two results together to get the final value of the expression. If no values are provided, the expression remains in its algebraic form as (2x + 6y).
the simplest form of 5x + 3y +2x - 6y is 7x-3y
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
5x + 6y + 3y - 2x you have to add like terms. add the y terms and then the x terms 9y + 3x this is your answer
it is -4
3(x+y)
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
the simplest form of 5x + 3y +2x - 6y is 7x-3y
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
(6,0) and (0,2)
5x + 6y + 3y - 2x you have to add like terms. add the y terms and then the x terms 9y + 3x this is your answer
6y
It is: 2(x+3y) when factored
it is -4
20x2 + 22xy + 6y2 = 20x2 + 10xy + 12xy + 6y2 = 10x(2x + y) + 6y(2x + y) = (2x + y)(10x + 6y) = 2(2x + y)(5x + 3y)
3(x+y)
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
2(x - 3y + 7z)
