Solve the system of equations. 2y+7x=-5 &5y-7x= 12 x=, y=

ASAP

x = -1 , y = 1

Step-by-step explanation:

2y+7x = -5

7x = -5 - 2y

5y-7x = 12

5y - (-5 - 2y) = 12

5y + 5 + 2y = 12

7y = 7

y = 1

7x = -5 - 2 = -7

x = -1

x = -1

y = 1

Step-by-step explanation:

2y + 7x = -5

5y - 7x = 12

Add both equations to eliminate 7x

7y = 7

Divide both sides by 7 to isolate y

7y/7 = 7/7

y = 1

Now substitute 1 for y in either equation to get x.

Using equation 1, we have

2y + 7x = -5

2 x 1 + 7x = -5

2 + 7x = -5

Subtract 2 from both sides to eliminate 2 on the left

2 - 2 + 7x = -5 - 2

7x = -7

Divide both sides by 7 to isolate x

7x/7 = -7/7

x = -1

x = -1

y = 1

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
