5 0

Answer:

x = -8

y = -10

Step-by-step explanation:

Elimination

2x - 3y = 14

5x - 3y = -10

__________--

-3x = 24

x = 24/-3

x = -8

Subsitution

2x - 3y = 14

2(-8) - 3y = 14

-16 - 3y = 14

-3y = 14 + 16

-3y = 30

y = 30/-3

y = -10

3z-4=6z-17 how do solve
Maru [420]
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=\frac{-13}{-3z} (divided both sides by -3z)
z=\frac{13}{3}
