If 2x + y = 2012, then the algebraic formula 2 (3x-2y) - (X-Y) + (- x + 9y)=

2(3x-2y)-(x-y)+(-x+9y)
=6x-4y-x+y-x+9y
=4x+6y
The title is wrong. Please check it

When x + y = 10, x + 3Y = 67, the value of the algebraic formula 3x square + 12xy + 9y square is

3x^2+12XY+9Y^2
=3(x^2+4XY+3Y^2)
=3(x+y)(x+3y)
Substituting x + y = 10, x + 3Y = 67
So = 3 * 10 * 67 = 2010

If the value of the 2nd power + 3Y + 3 of the algebraic formula 2x is 4, then the value of the 2nd power + 9y + 3 of the algebraic formula 6x is

If 2x 2 + 3Y + 3 = 4
Then: 2x 2 + 3Y = 1
∴6x²+9y+3
=3(2x²+3y)+3
=3×1+3
=3+3
=6

If the values of the algebraic expressions 4Y + 8 and 8y-7 are opposite to each other, then the value of Y is equal to several answers

The value of 4Y + 8 and 8y-7 are opposite to each other
4Y+8=-（8Y-7）
4Y+8=8Y+7
4Y-8Y=7-8
-4Y=-1
Y=1/4

If the value of the square of the algebraic expression 2Y + 3Y + 7 is 8, then the value of the square of the algebraic expression 4Y + 6y + 9 is?

2Y^2+3Y+7=8
2Y^2+3Y=1
4Y^2+6Y=2
4Y^2+6Y+9=11

If the value of the square of the algebraic expression 2Y + 3Y + 7 is 2, then the value of the square + 9 of the algebraic formula-6y-4y is______ -

2Y ^ 2 + 3Y + 7 = 2
So 2Y ^ 2 + 3Y = - 5
-6y-4y^2+9
=-2(2y^2+3y)+9
=-2×(-5)+9=10+9=19

If the value of 2Y ^ 2 + 3Y + 7 is 2, then the value of the algebraic expression 4Y ^ 2 + 6y-9 is?

If the value of 2Y? + 3Y + 7 is 2, then the value of the algebraic expression 4Y? + 6y-9 is?
4y²+6y-9
=2(2y²+3y+7)-23
=2*2-23
=-19

If the value of the square of the algebraic expression 2Y + 3Y + 7 is 2, then the square of the algebraic expression 4Y + 6y-9=

The square of 2Y + 3Y + 7 = 2
2Y squared + 3Y = 2-7 = - 5
4Y squared + 6y-9
=2 (2Y squared + 3Y) - 9
=-5*2-9
=-19

If the square of the polynomial 2Y + 3Y is 8, then the value of the square of 4Y + 6y-9 is?

2y^2+3y=8
4y^2+6y=16
The square of 4Y + 6y-9 = 16-9 = 7
