it think ot is 5(a+b)
To evaluate (5a + 5b) where (a = -6) and (b = -5), substitute the values into the expression: [ 5(-6) + 5(-5) = -30 - 25 = -55. ] Therefore, (5a + 5b = -55).
To simplify the expression (6a + 3b - 5a - 8b), combine like terms. For the (a) terms: (6a - 5a = 1a) or just (a). For the (b) terms: (3b - 8b = -5b). Thus, the simplified expression is (a - 5b).
10a + 5b
5b + 5b = 2 x 5b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
It is: 5a+5b
The expression is 5b + 16
To evaluate (5a + 5b) where (a = -6) and (b = -5), substitute the values into the expression: [ 5(-6) + 5(-5) = -30 - 25 = -55. ] Therefore, (5a + 5b = -55).

It is equivalent to 53a+44b when simplified
It is: 5(a+b)
10a + 5b
5b + 5b = 2 x 5b
5b
The expression is: (4a+b)/(2a-5b)
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
-5a + b = 2 AND -a - 5b = 0 -5a + b = 2 b = 2 + 5a *using above -a - 5b = 0 -a - 5(2 + 5a) = 0 -a - 10 - 25a = 0 -26a = 10 a = 10/-26 *using 'a' value 5a + b = 2 5(10/-26) + b = 2 -25/13 -2 = -b b = 51/13 Therefore a = 10/-26 b = 51/13
