-2b + 7 -3b = 2 -2b +7 -3b +2b = 2 + 2b 7 -3b + 3b = 2 + 2b +3b 7-2 = 2-2 + 2b + 3b 5 = 5b 1 = b
If b = 5 then 15-10 = 5
3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28
5
5 over 2 thats the answer
-2b+8-4b = -5-11b+7 -2b-4b+11b = -5+7-8 5b = -6 b = -6/5
If b = 5 then 15-10 = 5

-2b + 7 -3b = 2 -2b +7 -3b +2b = 2 + 2b 7 -3b + 3b = 2 + 2b +3b 7-2 = 2-2 + 2b + 3b 5 = 5b 1 = b
(2b - 5)(b + 7)
5b - 7 = 2b +55b-2b-7=2b -2b +5 subtract 2b from each side to get b on one side3b-7=53b-7+7 = 5+7 now add 7 to both sides to get the numbers on one side3b = 123b/3 = 12/3 finally divide both sides by 3 to solve for bb = 4
3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28
20a+10b-35
What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
It is 36.
