It simplifies to: 3b+17
If you mean: 7+2b = 1 then the value of b is -3
What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
a-b+a-b+2b+a = 4a
=2b
(2b - 5)(b + 7)
-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
To simplify the expression (3(a + b) + 2b(a + b)), we first factor out ((a + b)): [ = (a + b)(3 + 2b) ] This shows that the expression can be rewritten as the product of ((a + b)) and ((3 + 2b)).
3a + 2b = 4If b = 7, then3a + 2(7) = 43a + 14 = 4Subtract 14 from each side:3a = -10Divide each side by 3:a = -10/3
b=7
-b+5b-2b=2b
-2b+8-4b = -5-11b+7 -2b-4b+11b = -5+7-8 5b = -6 b = -6/5
To simplify the expression ( b + 5a + 7 - 3a - 2 + 2b ), first combine like terms. The ( b ) terms are ( b + 2b = 3b ), and the ( a ) terms are ( 5a - 3a = 2a ). For the constant terms, combine ( 7 - 2 = 5 ). Thus, the simplified expression is ( 3b + 2a + 5 ).
