(3r + 2)(r - 5)

r - 10 + 100 - 3r = -2r + 90

-16r=2 divide both sides by -16 and your answer is -1/8

5+3R = 5R-19bring all the variables to the left side (in this case it will be R)remember when you bring numbers or variables the sign changes, if the variable or number is positive it shall change to negative and vise versa.3R-5R= -19-5-2R = -24R= -24/-2= 12checking:5+3R = 5R-19so now you substitute R to see if it equation is correct.5+3(12)= 5(12)-195+36=60-1941=41 SO CORRECT!

(3r + 18)/12 = (4r - 48)/4Multiply both sides by 12: (3r + 18) = 3*(4r - 48)or: 3r + 18 = 12r - 144Subtract 3r from both sides: 18 = 9r - 144Add 144 to both sides: 162 = 9rDivide both sides by 9: 18 = rAnswer: r = 18

No, it's simply 3r, because multiplication (r multiplied by 3) comes first in the order of operations.

-2r(3r - 11)(3r + 11)

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

It is not correct to say that 8 plus 2 8r-2r 4 3r plus 2 r = 0

If: 3r-8 = 2-2r Then: 5r = 10 And: r = 2

r+3+2r=21 to solver this equation you have to first simplify then solve. you have to combine same variables. 3r+3=21 -3 -3 you subtract three to get r by itself (3r=18)/3 you divide by three to get r by itself Answer r=6

If: 3r-8 = 2-2r Then: 5r = 10 And: r = 2

(r + 1)(3r - 5)

7r = 3r - 527r (- 3r) = 3r - 52 (- 3r)4r = - 524r / 4 = -52 / 4r = -13

(3r + 2)(r - 5)
