8b -2a

(4, 3)

add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b

5b + 5b = 2 x 5b

ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.

7ab

What is the solution of -2a plus 3a plus 5b

The expression is: (4a+b)/(2a-5b)

√20a2b = √4a2 * √5b = 2a√5b the answer is 2a times radical 5b.

8b -2a

(4, 3)

add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b

10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5
