Answer:
7/11
Step-by-step explanation:
X+8y=18
-5x+3y=-4
Multiply the first equation by 5
Add the two equations together
5x+40y=90
-5x+3y=-4
43y=86
Y=2
Plug y into one equation to find x
X+16=18
X=2
A fraction can be viewed as a division problem, and a mixed number can be viewed as an addition problem. So,
7 29/80 can be read as:
7+29÷80
Follow the order of operations and you'll have your decimal.
7+29÷80
7+0.3625
7.3625
