Question

7(2+5v)=3v+14 AND 36-7p= -7(p-5) ANDDD
30+6p=7(p+6)-5

Answer 1

hope it helps mate your answer

Answer 2

( i ) : 7( 2 + 5v ) = 3v + 14

7( 2 ) + 7( 5v ) = 3v + 14

14 + 35v = 3v + 14

14 - 14 = 3v -35v

0 = - 32v

0 / 32 = v

0 = v

Therefore, value of v is 0.

( ii ) : 36 - 7p = -7( p - 5 )

36 - 7p = - 7( p ) - 7( - 5 )

36 - 7p = - 7p + 35

36 - 35 = 7p - 7p

1 = p( 7 - 7 )

1 = p( 0 )

1 / p = 0

1 / p = 0

p = 0 Or Undefined

Therefore the value of p is 0 or undefined.

( iii ) : 30 + 6p = 7( p + 6 ) - 5

30 + 6p = 7( p ) + 7( 6 ) - 5

30 + 6p = 7p + 42 - 5

30 + 6p = 7p + 37

30 - 37 =7p - 6p

- 7 = p

Therefore the value of p is -7.
