Choose the equivalent system of linear equations that will produce the same solution as the one given below.
6x + 2y = -6
3x - 4y = -18

a: 12x + 4y = -12
15x = -30

b: 8x + 4y = -4
14x = -10

c: 6x - 8y = -36
-6y = -42

d: 6x - y = -15
3y = 9

answer: the correct answer is -32

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
