Hello from MrBillDoesMath!
Answer:
y = 2x - 3
Discussion:
2x - y = 3 => add "y" to both sides
2x - y + y = 3 + y => as -y+y = 0
2x = 3 + y => subtract 3 from each side of the equation
2x-3 = y
Thank you,
MrB
Answer:
D
Step-by-step explanation:
You started at level ground and then went deeper which represents the negatives. After you stick a five foot pole in there it sticks up 2 feet.
Answer: a = 23, b = 21, c = 136
Step-by-step explanation:
Answer:
The correct answer is D) (-2, -1)
Step-by-step explanation:
In order to solve this system of equations, start by multiplying the entire first equation by 2. Then add the two equations together. This will get the y's to cancel and allow you to solve for x.
-4x + 2y = -10
3x - 2y = 12
---------------------
-x = 2
x = -2
Now that we have the value for x, we can find y by plugging the x value into either equation.
-2x + y = -5
-2(2) + y = -5
-4 + y = -5
y = -1
