X+ 3y = 1 -----(first equation)
-2x+7 = -23 ---(second equation)
-2x = -23-7
x = 30/2
x = 15
Now, Substitute the value of x in first equation,
15 + 3y = 1
3y = 1 - 15
y = -14/3
In short, Final Answers are: x = 15 & y = -14/3
Hope this helps!
Answer:
Find the common like terns in each expression!
Step-by-step explanation:
For example A:
+3y +2x -2y +5z
+3y -2y = 1y or y
Then sort by the greatest values:
5z+2x+1y
Answer:
Step-by-step explanation:
The total number of marbles is 24 + 36 + 60 = 120
Red: 24/120 = 1/5
Blue: 36/120 = 6/20 = 3/10
Yellow: 60 / 120 = 1/2
Answer: The answer is a polynomial in two variables with degree 3.
Step-by-step explanation: We are given to write the properties of the polynomial

We can see that the polynomial 'p' contains two unknown variables 'x' and 'y'.
Also, the degree of the polynomial is the degree of the expression 
Therefore, the degree of the polynomial will be 2 + 1 = 3.
Thus,
(i) the polynomial has two unknown variables 'x' and 'y', and
(ii) Its degree is 3.
