Answer:
just add the equation and solve it then the value of X could be found then put the value of X and the value of y can be found. Just like in the below
Step-by-step explanation:
X+y=3 ------------ equation 1
4x-y=7 ------------ equation 2
adding equation 1 and 2
X+y=3
+ 4x-y=7
-----------------
5x = 10
X = 10/5
X = 2
putting the value of X in equation 1
or, 2+y=3
or, y = 3-2
Thus, y = 1
Which equations? I think you forgot to post a picture.
Its known as the signature line
Answer:
No, √3 is not rational. If you need more of an explanation let me know
10.4375
12.875×2=25.75 46.625-25.75=20.875 20.875÷2=10.4375
