Answer:
0 > -5
Step-by-step explanation:
9w - 4w + 6 > 1 + 5w
add the similar variables
5w + 6 > 1 + 5w
subtract 6 from both sides
5w + 6 > 1 + 5w
-6 -6
5w > 5w - 5
simplify
5w > 5w -5
subtract 5 w from both sides
5w > 5w -5
-5w -5w
simplify
= 0 > -5

Answer:
x=3, y=-1
Step-by-step explanation:
We are already given an equation solved for x, making substitution much easier. We know x=4y+7, meaning we can put 4y+7 whenever we see x in the second equation
2x-6y=12
We substitute 4y+7 in place of x
2(4y+7)-6y=12
Now we only have one variable to work on, distribute the 2
8y+14-6y=12
Combine similar terms, 8y-6y=2y
2y+14=12
Subtract 14 from both sides
2y=-2
y=-1
Now we plug in -1 for y in the first equation to find x
x=4(-1)+7
x=-4+7
x=3
