which statement correctly explains how mari could find the solution to the following system of linear equations using elimination?
27-50--9
|-71+ 39-4

its a straight line parallel to the time axis

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

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
