Answer:
When I see an equation, I can make up a story that the equation might represent, explain what the variable represents in the story, and solve the equation.
I don't know the exact answer so I hope this helps
Answer:
-25
Step-by-step explanation:
You can round -98.5 to 100
Then round 3.8 to 4
Negative divided by positive is negative.
-100 ÷ 4 = -25
Answer:
x = 1, y = 2
Step-by-step explanation:
In the elimination method to solve a system of linear equations, one of the two equations is added/subtracted to the other, in order to eliminate one variable from the equation.
In this problem, we have the following two equations:
To solve the system, first we multiply by 2 both sides of the second equation, and we get:
So now the system is
Now we add the two equations, and we get:
So, we get
Now we can substitute this value of y into the eq.(2), and we get:
