1)5r+7=13+2r+3r
2)5r+7=13+5r
3)5r's cancel
7=13
4)Subtract thirteen on both sides
7 =13
-13 -13
5)Answer is no solution because -6 doesn't equal to 0.
-6=0

(3r + 2)(r - 5)
r - 10 + 100 - 3r = -2r + 90
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!
-16r=2 divide both sides by -16 and your answer is -1/8
(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
