Answer 1

(1)2.8v-v=54
1.8v=54
v=30

(2)x-2x-3x= -1-25--3/7+5/3
x= 6.19

(3)(x-2)(x-2)=(x+4)(x-4)
x=5

Answer 2

Hlo friend.. Nice question..

Here is ur answer :

1) 2.8v=54+v

2.8v - 1 v = 54

1.8v = 54

v= 54/1.8

v= 540/18

v = 30

2)x+3/7-2x-5/3 =3x-5/5-25

3x+9-14x-35 / 21 = 3x-5/-20

-11x-26/21=3x-5/20

-20(-11x-26)= 21(3x-5)

220x + 520 = 63x - 105

220x - 63x = - 105-520

157x = - 625

x= - 625/157

3) x-2/x-4 =x+4/x-2

(x-2)(x-2)= (x+4)(x-4)

x²+4-4x = x² - 16

x²-x²-4x= - 16-4

-4x = - 20

x= - 20/-4

x = 5
