Question

If 2a+5=3(2a-1),value of 'a' is
​

Answer 1

Answer:

VALUE OF A IS 1

HERE TAKE 2A AS COMMON FROM BOTH SIDES

SO, 2A  5 = 3 (-1)

THEN 2A 5 + 1 = 3

SO, 2A= 3/6

AFTER CALCULATION 2A= 1/2 {HERE BOTH IS DIVISIBLE BY 3}

SO, A=1/2 MULTIPLY BY 2 [ HERE 2 AND 2 WILL BE CUT]

SO THE VALUE OF A = 1

Step-by-step explanation:

Answer 2

Answer:

2a+5=3(2a-1)

2a+5=6a-3

2a-6a=-5-3

-4a=-8

a=2

checking LHS

2a+5,. a=2

4+5=9

RHS

3(4-1)

3*3

9

LHS =RHS
