Substitution method please help :3

Step-by-step explanation:
5x - y = 6 and -2x + y = 8
1/ 5x - y = 6
=> y = 5x - 6
2/ -2x + y = 8
Substitute 1/ into 2/ we will have:
-2x + (5x - 6) = 8
=> -2x + 5x - 6 = 8
=> 3x = 14
=> x = <=> y =
- However, the question asked for the final equation when adding 5x - y = 6 and -2x + y = 8 => The correct answer will be: 3x = 14

Hey there! :D
These are vertical angles. They have the same measure, so they are equal to each other.
Subtract 25 on both sides.
Subtract 2x on both sides.
Divide both sides by 4.
I hope this helps, and have a nice day!
