Vanessa wants to purchase a new cell phone plan. The two plans from which she can choose are shown below. Vanessa used the system of equations shown below to determine how many minutes she can talk on both plans for the monthly costs to be equal. When solving the system of equations, what is a reasonable solution? *

all but the second one

step-by-step explanation:

cuz that one goes over 180

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
