The 2x’s cancel out so you would combine the y’s and the other side of the equal sign to get 6y=30. You would then divide each side of the equal sign by 6 to get y alone, leaving you with y=5. Next, plug in the y to either the top or bottom equation. Plugging it in to the top, you would get 2x+4(5)=22. You would multiply 4 and 5 to then get 2x+20=22. Lastly, subtract 20 from both sides then divide by 2 to get x=1.
The answer is (1,5).

Answer:
2200
Step-by-step explanation:
Answer:
option C.
Step-by-step explanation:
we have
System A
---> first equation system A
----> second equation system A
Multiply the second equation by 4 both sides
Adds this equation to the first equation system A
----> first equation system B
----> second equation system B
so
The first equation of System B is obtained by adding the first equation of System A to 4 times the second equation of System A
The second equations are identical
therefore
They will have the same solution
Answer:
Step-by-step explanation:
To graph this equation, start by plugging in different numbers for X and solve for Y.
For example: When x=0, y=0+3 ⇒ the coordinate is (0,3)
When x=1, y=1+3 ⇒ (1,4)
If you do this enough times, dotting each new coordinate then connecting them in a straight line, you will get your graph.
