The sum of two numbers is zero.
x + y = 0
y = -x
<span>Twice the smaller number subtracted from 3 times the larger number is 10.
Let x represent the larger number and y represent the smaller number.
Twice the smaller number: 2y
3 times the larger number: 3x
</span>Twice the smaller number subtracted from 3 times the larger number is 10.
3x - 2y = 10
-2y = -3x + 10
y = 3/2 x - 5
The equations are:
y = -x
y = 3/2 x - 5
The answer is the first choice.

Answer:
The equation representing pounds of apples will has left
.
Will has left with 7 pounds of apples.
Step-by-step explanation:
Given:
Total pounds of apple = 20 pounds.
Pounds of apple used for apple sauce = 4 pounds
Pounds of apple used for apple butter = 6 pounds
Pounds of apple used for making juice = 3 pounds
We need to write the equation to represent pounds of apples will has left.
Solution:
Let us assume pounds of apples will has left be 'x'.
So we can say that;
pounds of apples will has left can be calculated by subtracting Pounds of apple used for apple sauce and Pounds of apple used for apple butter and Pounds of apple used for making juice from Total pounds of apple.
framing in equation form we get;

Hence The equation representing pounds of apples will has left
.
On Solving the above equation we get;

Hence Will has left with 7 pounds of apples.
Answer:
The width of the rectangular room =x= 8
Step-by-step explanation:
Given: A rectangular room is twice as long as it is wide, and its perimeter is 48 meters.
To find: The width of the room.
Solution: Let the width of the rectangular room= x meters, then the length of the rectangular room will be = 2x.
Now, Perimeter of rectangular room=2(l+b)
⇒48=2(2x+x)
⇒24=3x
⇒x=8 meters
Then, the width of the rectangular room =x= 8 meters and the breadth of the rectangular room=2x=2(8)=16 meters.
