Answer:
what question do u need help with???
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
-3 + (-4) 4 + (-3) is -6 I hope that helps because that what I got
2x + 4y = 14
4x + y = 20......multiply by -4
----------------
2x + 4y = 14
-16x - 4y = -80 (result of multiplying by -4)
---------------add
-14x = -66....as u can see, ur y's cancel out
so ur answer is : 1st answer choice <==
** and just so u know, u could have multiplied the 1st equation by -2, and it would have cancelled out ur x's
5(4) is 20. 10(8) is 80. 25(3) is 75. 20+80+75 equals 175. He has a total score of 175.
