Question
Solve the system of equations using the substitution method. State your final answer as an ordered pair. DO NOT include spaces in your answer.y=−4x−14𝑦=−4𝑥−14y=−2x−10𝑦=−2𝑥−10Solution:
Solution
The system of equations is:
- y = -4x - 14
- y = -2x - 10
To solve this system using the substitution method, we can substitute equation 2) into equation 1) because they are both equal to y.
So, -4x - 14 = -2x - 10
To solve for x, we can start by adding 4x to both sides to get rid of the -4x on the left side:
-14 = 2x - 10
Then, add 10 to both sides to get rid of the -10 on the right side:
-4 = 2x
Finally, divide both sides by 2 to solve for x:
x = -2
Now that we have x, we can substitute x = -2 into either of the original equations to solve for y. If we substitute it into the first equation:
y = -4(-2) - 14 y = 8 - 14 y = -6
So, the solution to the system of equations is (-2, -6).
