You're going to want to combine like terms first off, so 2x+3x=5x. Then you have 5x+7=-41. Now you subtract 7 from both sides, and basically undo that function so you have 5x=-48. Then you do the opposite of multiplying 5, so you divide five from both sides and get -9.6. So x=-9.6. Is that what you wanted? Because if not, ignore this.

1) (3/2)*(7/2)
2) (21/4)*(5/2)
3) Answer: 105/8
Answer:
-5
Step-by-step explanation:
First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)
This would look like:

This means the slope is -5.
Parallel lines always have the same slope, so the slope of the parallel line is also -5
