Answer:
y = -3
Step-by-step explanation:
y + 3 = 7(2 - 2)
y + 3 = 0
Subtract 3 from both sides
y + 3 - 3 = 0 - 3
y = -3
Answer:
5/28
Step-by-step explanation:
5/4 / 7 = 5/4 * 1/7 = 5/28
Answer:
B. and C. both equations has infinitely many solutions.
Step-by-step explanation:
- B. 3(4y-5)=12y-15 → 12y-15=12y-15
- C. 4(5y+2)=20y-6 → 20y+8=20y-6
In both the equations, value of y cannot be determined, so they have infinitely many solutions.
