If y is substitute into either of the original equation. The solution as an ordered pair are: x=-2; y=3.
<h3>The solution as an ordered pair</h3>
x + 3y= 7 equation 1
x+2y=4 equation 2
Solving for y
x+3y-(x+2y)=7-4
x+3y-z-2y=7-4
3y-2y=7-4
y=7-4
y=3
Substitute y=3 into equation 2
x+2y=4
x+2×3=4
x+6=4
Collect like terms
x=4-6
x=-2
Therefore the solution as an ordered pair are: x=-2; y=3.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Range is y thing, where as domain is an x thing. The way you state a range (or a domain, for that matter) is to start from the low point on the graph and go up to the high point. Our graph doesn't have a starting point; therefore, the "low" end of the graph comes up from -∞. The high point on the graph maxes out at 3. Therefore, the proper way to state the range (depending upon whether you use set-builder or not) is
R = (-∞, 3] or another way to state this is
R = {y | y ≤ 3} which reads "y such that y is less than or equal to 3".
