Answer choices:
A (3 , -4)
B (4 , -7/2)
C (-5 , 8)
D (5/2 , -17/4)​

D (5/2, -17/4)

Step-by-step explanation:  Using elimination your goal is to get rid or 1 variable  so you can solve for the one that's left.  By adding the -2y and 2y you will get 0.  You will also add the 3x+x (4x) and -1+11 (10).  You have now gotten rid of the y and have 4x=10.  By dividing each side by 4 we now know x =2.5.  D is the only possible solution with x=2.5 (5/2) but to solve for y you plug 2.5 in to an equation as x so) x-2y=11

                                                                           2.5-2y=11

                                                                            -2y=8.5                                                                        Answer D (5/2,-17/4)                                      y=-17/4 (4.25)

x=16/11 in decimal form 1.45

Step-by-step explanation: 1/2 (−4+12)+3( 1/3x+6)=3/4(16x+8)

4+x+18=12x+6

(x)+(4+18)=12x+6(Combine Like Terms)

x+22=12x+6

x+22=12x+6

Step 2: Subtract 12x from both sides.

x+22−12x=12x+6−12x

−11x+22=6

Step 3: Subtract 22 from both sides.

−11x+22−22=6−22

−11x=−16

Step 4: Divide both sides by -11.

-11x/-11=-16/-11

x=16/11 or 1.45
