-16r=2 divide both sides by -16 and your answer is -1/8
(3r + 2)(r - 5)
4r +3 = 3r-2 r + 3=-2 r=-5 basically collect terms so that you get one coefficient of r (in this case 4r on one side and 3r on the other. To get the three r over to the other side you subtract 3r on both sides.) Then r+ 3=-2, so that's simple algebraic manipulation.
3r - 9r = 18 wright equaton -6r = 18 combine like terms r = -3 solve
r - 10 + 100 - 3r = -2r + 90
3r-2 for r=65
17 = 13 - 3r Subtract 13 from bith sides: 4 = -3r Divide both sides by -3 : -4/3 = r or r = -1.3...
-16r=2 divide both sides by -16 and your answer is -1/8
3r-r equals 12 = -9
(3r + 2)(r - 5)
-3r-13r = 2 -16r = 2 or 16r = -2 r = -(2/16) = -(1/8)
so -10r = 2 so r = -0.2
4r +3 = 3r-2 r + 3=-2 r=-5 basically collect terms so that you get one coefficient of r (in this case 4r on one side and 3r on the other. To get the three r over to the other side you subtract 3r on both sides.) Then r+ 3=-2, so that's simple algebraic manipulation.
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
If: -5 = 7+3r then the value of r works out as -4
If: 3r-8 = 2-2r Then: 5r = 10 And: r = 2
3r+10=5r-46 --> add 46 to both sides 3r+10+46=5r-46+46 3r+56=5r --> subtract 3r from both sides 3r+56-3r=5r-3r 56=2r --> divide both sides by 2 56/2=2r/2 28=r
