Aset of equations is shown above. which method eliminates one of the variables? a) multiply equation a by -1/3 and add the result to equation b. b) multiply equation b by 3 and add the result to equation a. c) multply equation a by 2 and equation b by -6 and add the results together. d) multiply equation b by 5 and equation a by 4 and add the results together.

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)

i hope i

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
