Rewrite 5/ 16 + 6/ 20 with a common denominator.
Troyanec [42]
25/80 + 24/80 = 49/80. 16 and 20 both go into 80. !6 goes in 5 times so you multiply 5 by 5. 20 goes into 80 4 times so you multiply 4 by 4. 24/80 + 25/80 = 49/80.

Ill mark as brainliest
crimeas [40]

Answer: x =-7 and y =10

Step-by-step explanation:

The given system of equations :

4x-y=-38..................(1)\\x+y=3...........................(2)

Add equation (1) and (2), we get

4x+x-y+y=-38+3\\\\\Rightarrow5x=-35\\\\\Rightarrow\ x=\frac{-35}{5}=-7\\\\\Rightarrow\ x=-7

Put value of x in (2), we get

-7+y=3\\\\\Rightarrow\ y=3+7=10

hence, the solution of the given system is  x =-7 and y =10.
