2y-9x equals 14 solve for y?

2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2


What is 9x-2y equals 14 in function form?

If: 9x-2y = 14 Then: y = 4.5x-7 in slope intercept form


What expresssion represents the sum of (7x-3y) and (2x plus 5y)?

(7x-3y) + (2x+5y) = 9x+2y


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 slope intercept form of 9x-2y7?

If you mean: 9x-2y = 7 then it is y = 4.5x-3.5


9x-2y 18 what is the answer to this?

There is no equation in the question: only an expression. An expression has no answer.


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


What is the system of equations and enter the solution as an ordered pair 9x - 2y equals 73 5x - 9y equals 9?

(1) 9x-2y=73 (2) 5x-9y=9 from (1) 9x-2y+2y=73+2y => 9x= 73+2y => x = (73+2y)/9 put into (2) 5x-9y = 9 => 5(73+2y)/9 - 9y=9 => 10y/9 + 365/9 -9y = 9 => 10y/9 - 9y = 9 -365/9 = -284/9 => -71y/9 = -284/9 => 71y= 284 => y = 284/71 = 4 and x = (73+2*4) / 9 = 9


-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
