Answer:

-15, 3

Step-by-step explanation:

3|x+6| -7 = 20

3|x +6| = 27 . . . . add 7

|x +6| = 9 . . . . . . divide by 3

This resolves to two equations:

x + 6 = 9

x = 3 . . . . . subtract 6

and

x + 6 = -9

x = -15 . . . . subtract 6

Which ordered pair is the best estimate of the solution of the system 3x+y=4 x-3y=4?

vovangra [49]

$3x+y=4\ \ \ \ \ \ ..............equation(1)\\x-3y=4\ \ \ \ \ \ ..............equation(2)\\\\ Using~equation~(2), \\\\
x-3y=4\\x=4+3y\\\\Now,\ using\ the\ value\ of\ x\ in\ equation\ (1),\ we\ get,\\\\(4+3y)-3y=4\\\\4=4$

Since all the variables cancel out and the coefficient equal to eachother, this system of equation has <u>infinitely many solutions!</u>
