I need help with all of the following !!

Here’s number 1:

1. 0r=5(r-4)
0r=5(r)+(5)(-4) (Distrubute)
0=5r-20
5r-20=0
5r-20+20=0+20 (add 20 to both sides)
5r=20
5r/5 = 20/5 (Divide both sides by 5)
r=4

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
