Answer:
see the explanation
Step-by-step explanation:
we have
we know that
To cross multiply, start by multiplying the numerator of the left-hand fraction by the denominator of the right-hand fraction.
2(8)
Then, multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction.
7(28)
Next, set the 2 products equal to each other.
2(8)=7(28)
Answer:
❤️❤️ your answer is either 1 or 9 and i show the work for when you get the answer 1 and the work for haw you get the answer 9 if there is something wrong with my problem just let me know thanks ❤️❤️
Step-by-step explanation:
3x+4(8)=5x+2(7)
3x+32=5x+14
-14 -14
3x+18=5x
-3x -3x
18=2x
x=9
__________________________________________________________
3x+4=5x+2
-2 -2
3x+2=5x
-3x -3x
2=2x
x=1
I don’t get what you are asking ? make a number like and draw the fraction 1/5
The given operation involves just swapping the two rows, so carrying out
on the matrix gives
![\left[\begin{array}{cc|c}5&5&5\\1&-\dfrac23&5\end{array}\right]\to\left[\begin{array}{cc|c}1&-\dfrac23&5\\5&5&5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D5%265%265%5C%5C1%26-%5Cdfrac23%265%5Cend%7Barray%7D%5Cright%5D%5Cto%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%26-%5Cdfrac23%265%5C%5C5%265%265%5Cend%7Barray%7D%5Cright%5D)
