Start with simplifying: 2a + -3 = 5 and reordering: -3 + 2a = 5. Then add '3' to each side of the equation: -3 + 3 + 2a = 5 + 3 and you get 2a = 8 once all like terms are combined. The last step is to divide both sides by 2 and you get the answer, which is a = 4.

(6a3 - 19a2 + 15a)/(2a - 3) = a(6a2 - 19a + 15)/(2a - 3) = a(2a - 3)(3a -5)/(2a -3) = a(3a - 5)
To simplify the expression 2a - 3 + 4b - 2a - b - 3 + 5, we first combine like terms. Combining the terms with 'a', we have 2a - 2a = 0. Combining the terms with 'b', we have 4b - b = 3b. Combining the constants, we have -3 - 3 + 5 = -1. Therefore, the simplified expression is 3b - 1.
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
9a +8 -2a -3 -5a = 2a +5
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
