10a + 5b
5b + 5b = 2 x 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
ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.
It is: 5a+5b
The expression is 5b + 16
It is equivalent to 53a+44b when simplified
It is: 5(a+b)
10a + 5b
5b + 5b = 2 x 5b
The expression is: (4a+b)/(2a-5b)
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
It is an expression that can be simplified to: 3a-2b+c
It is 9
