Without an equality sign and not knowing the plus or minus values of some of the given terms it can't be considered to be an equation.
An equation does not need variables. 4+5=9 is an equation as is 5+W=9
Assuming the point is (9, -4), the equation is y = -4.
Try elimination.4X + 13Y = 40- 1(4X + 3Y = - 40)4X + 13Y = 40- 4X - 3Y = 40-----------------------add10Y = 80Y = 8-------------find X ( top equation )4X + 13(8) = 404X + 104 = 404X = - 64X = - 16----------------------check in both equations for consistency4(- 16) + 13(8) = 40- 64 + 104 = 4040 = 40-------------top checks4(- 16) + 3(8) = - 40- 64 + 24 = - 40- 40 = - 40-------------------both check and are consistentSo, X is,- 16 ( while Y is 8 )
Equation of circle: (x-2)^2 +(y+9)^2 = 49
The straight line equation works out as: 3y = x
42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
(2y + 5)(y - 9)
(x - 13y)(x + 13y)
9x - 3(x + 13y) = 9x - 3x - 39y = 6x - 39y = 3(2x - 13y)
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
If y2 + 13y = 40, then y ~ 15.55If y2 + 13y = 0, then y = -13Improved Answer:-y2+13y+40 = 0(y+5)(y+8) = 0Therefore: y = -5 and y = -8
-26x
It is an equation: n - 9 = 9It is an equation: n - 9 = 9It is an equation: n - 9 = 9It is an equation: n - 9 = 9
This simplifies to 6+13y If you meant 9+7y-(3+6y) then it becomes 6+y It is not clear from the problem which you meant.
(y2+13y+22)/(y+2) = (y+11)
y= -3/13​​
If you mean: 4y^2 +3 -13y then the expression is (4y-1)(y-3) when factored
