The left side 4+5m is the same as 5m+4

Simplifying the right hand side has 4m+1+m turn into 5m+1

The original equation is equivalent to 5m+4 = 5m+1

If we subtract 5m from both sides, the 5m terms cancel leaving us with 4 = 1, but that's not a true statement.

Regardless of whatever value you pick for m, the original equation will not be true.

your answer would be 12

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
