9y - 9 = -117 9y - 9 + 9 = -117 + 9 9y = -108 9y/9 = -108/9 y= -12
314-9y = 305
9y-11=7 +11 +11 9y=18 y=2
-3x+9y=18; find the x and y intercept of the line
Yes, 6 and 9y are unlike terms. The 6 is a constant and 9y is constant attached to a variable.
To find the value of ( y ) when ( x = 11 ), we can substitute ( x ) with 11 in the equation ( 7x - 9y = 23 ) and solve for ( y ): [ 7(11) - 9y = 23 ] [ 77 - 9y = 23 ] [ -9y = 23 - 77 ] [ -9y = -54 ] [ y = \frac{-54}{-9} ] [ y = 6 ] So, when ( x = 11 ), ( y = 6 ).
9y - 9 = -117 9y - 9 + 9 = -117 + 9 9y = -108 9y/9 = -108/9 y= -12
-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
314-9y = 305
9y-3 = 6
-9y-15x ---- -3
9y - 4x
9y-11=7 +11 +11 9y=18 y=2
I assume you are solving for y. First you need to form an equation since you don't have an equal sign. The equation would be 9y - 818 - 4y = 0. Next, you have to isolate the unkown number from the known number by adding 818 to both sides of the equation and you would have 9y - 818 - 4y + 818 = 0 + 818, then your equation would read 9y - 4y = 818. Simplify the unknown number by subtracting 4y from 9y which now makes the equation 5y = 818. To find the value of y, divide both sides of the equation by 5. Hence 5y/5 = 818/5. Thus, y = 163.6. To prove the solution, substitute 163.6 for y and solve.
x2 - 81y2 = (x + 9y) (x - 9y)The actual numerical value depends on the values of 'x' and 'y'.
4x2 - 9y Not factorable from what I see.
