Question

Hi! Can someone help me with this? Thanks!

Directions: Solve this equation by doing it twice; one time using the substitution method and one time using the graphing method.

x + 2y = 1
5x – 4y = -23

Answer 1

x = 1-2y

5x -4y = -23

5(1 -2y) - 4y = -23
5 - 10y - 4y = -23
5 - 14y = -23
5 - 5 - 14y = - 23 -5
- 14y = -28
y = 2
x = 1- 2(2)
x = -3
(-3, 2)
