Answer 1

( 3 . x - 2⁴ ) . 7³ = 2 . 7⁴

( 3 . x - 16 ) . 343 = 2 . 2041

( 3 . x - 16 ) . 343 = 4802

3 . x - 16 = 4802 : 343 

3 . x - 16 =  14

3 . x = 14 + 16

3 . x = 30

    x = 30 : 3

     x = 10

Answer 2

(3.x-2⁴).7³=2.7⁴

3.x-2⁴=2.7⁴:7³

3.x-2⁴=2.7

3.x-2⁴=14

3.x-16=14

3.x=14+16

3.x=30

x=30:3

x=10
