The two equations that can be formed by adding or subtracting is
4x−4y = 16 and 2x − 6y = -8 .
the two equations are : x + y = 12 and 3x − 5y = 4
Adding we get :
x + y = 12
<u>3x − 5y = 4</u>
4x -4y = 16
Subtracting we get:
x + y = 12
<u>3x − 5y = 4</u>
-2x + 6y = 8 or 2x - 6y = -8
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the unknown parameters variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign.
It will be regarded as a phrase. In the following section of this article, you will discover the distinction between an equation and an expression.

Since y represents miles and x represents weeks, it would be y=300x
The measure of angle θ is 7π/6
The measure of its reference angle is pi/6
And sin <span>θ is -1/2
Hope it helped :) </span>
Answer: 18 is the constant rate an i don't know what to put in the x an y sorry got some <em>work of my own to do!!!</em>
1 = 1
2=1.125
3=0.375
4= not enough information
