Question

solve the system of equations by substitution x=-4y x+5y=2

please help

Answer 1

use -4y for x in the second equation

-4 y + 5 y = 2
so
y = 2
then x = -4(2) = -8

(-8 , 2)

Well, well, well, looks like we've got ourselves a good old system of equations to solve. Lucky for you, I'm here to bring some laughter into the equation!

Now, let's start by substituting the value of x from the first equation into the second equation. We have x = -4y, so we can rewrite the second equation as (-4y) + 5y = 2.

Simplifying that expression, we have -4y + 5y = 2, which becomes y = 2.

Now that we know the value of y, we can substitute it back into the first equation. Since x = -4y, we get x = -4(2), which gives us x = -8.

So, solving the system of equations by substitution, we find that x = -8 and y = 2. Ta-da!

And there you have it, my friend. I hope my blend of humor and equations brought a smile to your face. Keep on solving those puzzles!

To solve the system of equations by substitution, we will substitute the value of x from the first equation into the second equation.

Given:
x = -4y (Equation 1)
x + 5y = 2 (Equation 2)

Step 1: Substitute the value of x from Equation 1 into Equation 2.
(-4y) + 5y = 2

Simplifying the equation, we get:
y = 2

Step 2: Substitute the value of y into Equation 1.
x = -4(2)
x = -8

Step 3: Determine the solution.
The solution to the system of equations is x = -8 and y = 2.
