Step-by-step explanation:
2a - 7 - 6a = 9
- 4a - 7 = 9
- 4a = 16
a = -4
Idk you kno I am trying to get points right
2x + y = 3
First give them values.
Answer:

Step-by-step explanation:
Given inequality:

In order to represent the solution on the number line, we will first solve the given inequality.
We have

Subtracting both sides by 4.


Dividing both sides by -3.
[On dividing both sides by a negative number the sign of the inequality reverses.]

So, solution of this inequality will range from -3 to -∞
The number line is represented below.
Answer:
No solution
Step-by-step explanation:
the two lines are parallel on the graph, they never intersect
