Using elimination, we add the equations, but this time from left to right. This process wants to elimination a variable. So 2x plus -2x equals 0. Moving on the next variable, 6y plus -y is 5y. On to the last variable, 18 plus 12 is 30. So we have this equation, 5y=30. 30/5 is 6, so y=6. We plug 6 into y in one of the equations you choose. In this case, I'm going to use the first equation. Plugging 6, we have this equation, 2x plus 36 is 18. 18-36 is -18. We then have this equation, 2x=-18. We know -9 times 2 is -18, so our x value is -9, So, our y=6, and our x=-9.
Answer:
hey here's your answer!☺️
since number = n
so, 5 times of number = 5×n = 5n
and , 30 more than 8 times the number = 8n + 30
so, According to the question,
equation formed :-
" 5n = 8n + 30 "
hope it is helpful ✌️!
7 + x/4 = 5 (common denominator is 4)
4(7+x/4) = 4 x 5 (distribute the 4 though parenthesis)
4 *7 +4x/4 = 4 x 5
4 * 7 + x = 4 x 5
28 + x = 4 x 5
28 + x = 20 (subtract the 28)
x = 20 - 28
x = -8
Answer:
400k
Step-by-step explanation:
the reason why is bcz youre gay jk haha its because you have to mulitply 650 by 2 then square it divide by 2 and then cube it then you will have to do the quadraric formula to get your answer
Answer:
100x=256.25
Step-by-step explanation:
x/1025=25/100
What is 25% of 1025
that would be 1025×25
100x=256.25
