3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
12 = r/3 + 16
13r+10=5r-46 r= r = -7
so 26 = 4r so r = 6½
You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7
3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
r=2
10+r = 2r Subtract r from both sides:- r = 10
12 = r/3 + 16
13r+10=5r-46 r= r = -7
The answer is 10 because 12 divided by 3 equals 4... and plus 7= 10
so 26 = 4r so r = 6½
You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7
36
(3r + 2)(r - 5)
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
1.2 = (10+R)/30 x30 36=10+R -10 26 = R OR, as your question is unclear: 1.2 = 10 + (R/30) x30 36 = 360 + R -360 -324 = R
