10y = 2y - 6y + 7
10y =-4y + 7
10y +4y = 7
14y = 7
y = 1/2 = .5

What is 10X plus 6Y equals 100 if 6X plus 10Y equals 92?
X=7 y=5
If x equals 6 and y equals 7 then 3x plus 10y equals?
18 + 70 ie 87
3x plus 10y equals 7 -8x - 4y equals 17?
Multiply the first by 8 and the second by 3
What is 11x plus 10y equals 147 and 0x plus 2y equals 14 using elimination method?
Multiply all terms in the second equation by 5: 11x+10y = 147 0x+10y = 70 Subtract the second equation from the first equation in order to eliminate y: 11x = 77 Divde both sides by 11 in order to find the value of x: x = 7 Substitute the value of x into the original equations to find the value of y: Therefore it follows that x = 7 and y = 7
What is 5 plus 7 plus 7 plus 5 equals?
It equals 24.
What is 10X plus 6Y equals 100 if 6X plus 10Y equals 92?
X=7 y=5
If x equals 6 and y equals 7 then 3x plus 10y equals?
18 + 70 ie 87
3x plus 10y equals 7 -8x - 4y equals 17?

How do you prove that lines 12x-5y plus 3 equals 0 and 24x-10y-7 equals 0 are parallel?
12x-5y+3 = 0 => y = 2.4x+0.6 24x-10y-7 => y = 2.4x-0.292 rounded to 3 d.p. Both lines have the same slope but different y intercepts therefore they are parallel to each other.
What is 5 plus 7 plus 7 plus 5 equals?
It equals 24.
If 2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 9 plus 7 equals 96 9 plus 7 equals what?
96
Why is -7 plus -5 equals -2?
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 Then 9 plus 7 equals?
If I am correct, 9 plus 7 equals 112.
2 plus 3 equals 8 3 plus 7 equals 27 4 plus 5 equals 32 5 plus 8 equals 60 6 plus 7 equals 72 7 plus 8 equals what?
89
What is the center and the radius of the circle x2 plus y2 equals 12x -10y -12?
Equation of circle: x^2 +y^2 = 12x-10y-12 Completing the squares: (x-6)^2 +(y+5)^2 = 49 So center of circle is at (6, -5) and its radius is 7 units
What is 7 plus 7 plus 7 plus 7 plus 7 equals?
35
