Answer:
y = - [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
6x - 3y = - 7 → (1)
2x + 3y = - 9 → (2)
multiplying (2) by - 3 and adding to (1) will eliminate x
- 6x - 9y = 27 → (3)
add (1) and (3) term by term to eliminate x
0 - 12y = 20
- 12y = 20 ( divide both sides by - 12 )
y = [tex]\frac{20}{-12}[/tex] = - [tex]\frac{5}{3}[/tex]
