for all of these, you just have to divide by -1 to make the variable positive however you have flip the inequality sign when you divide by a negative number.
c > 1
-2 > v
y > 1
z > 6
1 > w
Answer:
its correct
Step-by-step explanation:
I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
