Question Details
Solve
-4x – 6y = 0
-6x- 12y = 18

x = 9

Step-by-step explanation:

-6x -12y = 18

multiply -4x -6y = 0 by -2 to get 8x + 12y = 0

the 12y's cancel out and you combine the equations to get 2x = 18

2x/2 = 18/2

x = 9

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
