Solve:

4 + 5x < 29

5x < 4 +29

5x < -4 +29

5x=-25

Solution set is x|x < -5

4x+5y=7

5x-4y=5

The lines are parallel am I right

5x < 25; therefore x < 5

Your "solution set" is wrong.

Your last pair of equations seems to go with a different question. The lines are NOT parallel. They are perpendicular.

I believe you asked the same question yesterday, at least the second one is the same.

Don't you go back to see if your questions get answered?

for the first one, from ...

5x < -4 +29

5x < 25

x < 5

so {x│x < 5}
