Which equation is the result of adding these two equations?

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

[A] 5x = 4 [B] 9x = 4
[C] -5x = -14 [D] 9x = 14
[C] -5x = -14

Adding the equations :

2x + 7x = - 5 + 9

9x = 4

Thus the answer is [B]

what do you mean by fog

step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
