(+)2=42

(

2+2+2=16

∴2+2=16+2×12=40

∴

Now, (−)2=2+2−2=40+2×12=64

A set of equations is shown above. Which method eliminates one of the variables? A) Multiply equation A by -1/3 and add the resu
Paraphin [41]

Answer:


Step-by-step explanation:

Multiplying Equation A by (1/3) and adding the result to Equation B will do the trick.  Let's actually solve the problem!

Equation A:  (5/3)x + 3y = 12

Equation B:    4x     -  3y = 8

                    ---------------------------

                     (5/3 + 12/3)x = 15        Note how this has eliminated the variable

                            (17/3)x = 15           y.

                                   x = (3/17)(15)
