9x + 2y = -11
I'm sorry to say this, but it is absolutely "impossible" to figure variables out with only one equality. You need one more of that to get those two variables (if you have only one variable it is perfectly fine and you can do it)

-5x plus 2y equals 6 -9x plus 2y equals 22?
Subtract first from second gives -4x = 16 so x = -4 and y = -7
6x plus 11 equals 92-3x?
6x+11=92-3x +3x +3x 9x+11=92 -11 -11 9x=81 divide by 9 x=9
If x equals 10 and y equals 10 then 9x plus 8y equals?
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
What is 9x plus 27 equals -81?
9x+27 = -81 9x = -81-27 9x = -108 x = -12
How can you get coefficients that are equal for y. 3x plus 5y equals 7 2x plus 15y equals 11?
Multiply the first equation by 3 to give 9x + 15y = 21
2y-9x equals 14 solve for y?
2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2
-5x plus 2y equals 6 -9x plus 2y equals 22?
Subtract first from second gives -4x = 16 so x = -4 and y = -7
9x plus 3x-9x equals 6 plus 8x-11?
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
How do you solve 6x-4y equals 54 -9x plus 2y equals -69 using substitution?
-9x + 2y = -69 So 2y = 9x - 69 The other equation can be written as 6x - 4y = 54 or 6x - 2*2y = 54 Substituting for 2y gives 6x - 2*(9x - 69) = 54 6x - 18x + 138 = 54 12x = 84 x = 7 and then 2y = 9x - 69 = 9*7 - 69 = 63-69 = -6 so that y = -3
What is the answer to 6x plus 47 equals 9x plus 11?
6x + 47 = 9x + 11 6x + 36 = 9x 36 = 3x 12 = x
How do you solve this system algebracally 9x plus 2y equals 5 and y-2x plus 3 equals 0?
9x + 2y = 5 y - 2x + 3 = 0 Put both equations into the same format. It is often easiest to have just one unknown on (say) the left-hand side of the equation. Let's pick y for this purpose. 2y = -9x + 5 y = 2x - 3 Now make the coeficients of y the same. This can be done by multiplying the 2nd equation by 2. 2y = -9x + 5 2y = 4x - 6 Then, -9x + 5 = 4x - 6 13x = 11 : x = 11/13 And substitue for x in any equation - take the very first original equation. 9x + 2y = 5 99/13 + 2y = 5 : 2y = 5 - 78/13 = - 28/13 y = - 14/13
-x-2y plus 9x-y plus 3x?
- x - 2y + 9x - y + 3x = 0 1.) Add like - terms 11x - 3y = 0 x = - 3/11y y = 11/3y
What is 9x-2y equals 14 in function form?
If: 9x-2y = 14 Then: y = 4.5x-7 in slope intercept form
9x-11 equals 6x plus 1?
9x-11 = 6x+1 9x-6x = 1+11 3x = 12 x = 4
What is the answer to 9x plus 3-2x equals -11?
X= -2
What expresssion represents the sum of (7x-3y) and (2x plus 5y)?
(7x-3y) + (2x+5y) = 9x+2y
Value of x when 5x plus 51 equals 9x plus 11?
5x + 51 = 9x + 11 Becomes 40 = 4x So x = 10
