What is 6x plus 3y plus 6y-2x?
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
What is 2x plus 9y - 6x?
9y - 4x
What does 12x plus 9y equivalent to?
It is equivalent to 3(4x+3y) when factored
What is 4y plus 3w plus 4x plus 9y plus 7x-7w?
4y + 3w + 4x + 9y + 7x - 7w (combine like terms)-4w + 11x + 13y
What does 12y plus 3 equals 9y-15 equal?
12y+3=9y-15 3y=-18 y=-6
What is 6x plus 3y plus 6y-2x?
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
P 2x-9y q 5y plus 6-4x r 3x plus 3y-5 then p plus q plus r?
p + q + r = (2x - 9y) + (5y + 6 - 4x) + (3x + 3y - 5) = x - y + 1
What is 2x plus 9y - 6x?
9y - 4x
What does 12x plus 9y equivalent to?
It is equivalent to 3(4x+3y) when factored

What does 4x-3y equals 1 2x plus 3y equals 2 equal?
second equation x 2: 4x + 6y = 4 subtract first equation: 9y = 3 so y = 1/3 and x = 1/2
2x plus 3y equals 3 and 4x minus 3y equals 9. What value of y is part of the solution for this system of equations?
There are two simultaneous equations, so to solve for y, eliminate x: 1) 2x + 3y = 3 2) 4x - 3y = 9 Multiply equation (1) by 2 giving: 1) 4x + 6y = 6 2) 4x - 3y = 9 Next, subtract equation (2) from equation (1), giving: (4x - 4x) + (6y - -3y) = 6 - 9 → 9y = -3 → y = -1/3
4x plus 3y equals -15 2x-3y equals -3?
4x+3y=-15 2x-3y=-3 Take second equation and multiply the whole with 2 so that when subtracting the two equations we can cancel out x. so it becomes 4x-6y=-6 4x +3y = -15 ( - ) 4x -6y = -6 ---------------------------------- 0x + (+3-(-6))y = -15 - (-6)) 9y = -9 .. or y=-1 So take any one equation and find x by substituting y value 2x - 3(-1)= -3 2x +3 = -3 2x = -6 x = -3 So x = -3, y = -1
Solve this polyinomal 5x plus 6y plus 3y-2x?
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
What is 2x plus 3y minus 2 plus3x plus 6y plus 7?
It is an algebraic expression that can be simplified to: 5x+9y+5
What value of b will make 2x-3y equals 5 and 9y plus bx equals 4 parallel?
2x - 3y = 5 => 3y = 2x - 5 has a gradient of 2/3 9y + bx = 4 => 9y = -bx + 4 has a gradient of -b/9 The two gradiends must be the same if the two lines are parallel: 2/3 = -b/9 so that b = -6
