Solve the system of equations below x - y = 5 2x - 3y = 4

x=11 y=6

Step-by-step explanation:

making x the subject in the first equation we get

x=y+5 put that in the second equation we also get

2(y+5)-3y=4

2y+10-3y=4

-y=4-10

-y=-6

y=6 use that to also find x from the equation x=y+5 we get

x=6+5

x=11

therefore x=11 y=6

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
