How to solve the problem

Mathematics
1 answer:

4 0
-3 1/2 -(-12 1/4)
-3 1/2 + 12 1/4
-3 1/2 = -7/2 = -14/4
12 1/4 = 49/4
-14/4 + 49/4 = 35/4 
35/4 = 8 3/4
A quick way to convert a mixed number to improper form (improper form makes it alot easier to add, subtract, and more), is like this:
a b/c
((a*c)+b)/c
This will get you the improper form of a fraction.
I hope this makes sense.

Solve the system of equations.<br><br><br> −5x+2y=9<br> y=7x<br> ​
RUDIKE [14]

Answer:

x=1  y=7

Step-by-step explanation:

−5x+2y=9

y=7x

Substitute the second equation into the first

-5x +2(7x) = 9

Distribute

-5x +14x = 9

Combine like terms

9x=9

Divide by 9

9x/9 =9/9

x= 1

Now find y

y = 7(1)

y = 7
