Question

If a = (2a-3)and b=(5-3a) be two algebraic expressions such that 2a +b =6, then find the value of a

Answer 1

Answer:

a=7 b=-8

Step-by-step explanation:

2(2a-3)+(5-3a)=6

4a-6+5-3a=6

a-1=6

a=7

b=6-2a=6-14=-8

Answer 2

The correct answer is "7".

Step-by-step explanation:

$The \ given \ values \ are:\\\\a=(2a-3)\\\\b=(5-3a)\\\\2a=2(2a-3)\\\\2a=(4a-6)\\\\Now,\\\\2a+b=6\\\\On \ putting \ the \ values \ in \ the \ above \ expression,we \ get\\\\(4a-6)+(5-3a)=6\\\\4a-6+5-3a=6\\\\a-1=6\\\\a=6+1\\\\a=7$
