Question

(4x - 1)(x + 2) = 2 +7 x​

Answer 1

Answer:

8 ∙ 2x = 5(y+8).

or, 8 ∙ 2x = 5(-8+8).

or, 2x = 50.

or, 2x = 1 [anything to the power 0 is 1 then, 50 = 1].

Taking log on both sides,

log 2x = log 1.

or, x log 2 = 0 [since log 1 = 0].

or, x = 0/log 2 [

Answer 2

4x+x-1+2=2+7x

5x+2=2+7x

2-2=7x-5x

0=2x

x=0/2
