Vhat should be done to these equations in order to solve a system of equations by elimination? 1-3x + 2y = 16
12x + 5y = 21
Multiply the first equation by 3 and the second equations by 2.
Multiply the first equation by 2 and the second equation by 3.
Multiply the first equation by 3.
Nothing needs to be done, since they both equal have 2's and 3's for coefficients.

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

im pretty sure its

(8,15)
