Sierra Hendricks · Answer 1

C

Step-by-step explanation:

2nd equation:

x - 3y + 3y = 14-3y

x = 14 - 3y

solving for y:

3 * (14-3y) - 2y = - 2

y = 4

y = 4 - > x = 2

and you can fill in both values to check it

3x - 2y = - 2x + 3y = 14To solve this system by substitution, which expression could be substituted for x?A) 3y + 14B) 3y - 14C) - 3y + 14D) - 3y - 14
