Answer:
m=5
Step-by-step explanation:
Firstly we know we are solving for M.
So we start like this.
[tex]3(5m - 7) + 4 = 8m + 1 [/tex]
use the distributive property to multiply 3 by 5m-7=
[tex]15m - 21 + 4 =8m + 18[/tex]
Add -21 and 3 to get -17
[tex]15m - 17 = 8m + 16[/tex]
subtract 8m from both sides
[tex]15 m - 17 - 8m = 18[/tex]
combine 15m and -8m to get 8m
[tex]7m - 17 = 18[/tex]
Add 17 to both sides
[tex]7m = 18 + 17[/tex]
Add 18 and 17 to get 35
[tex]7m = 35[/tex]
Divide both sides by 7
[tex]m = \binom{35}{7} [/tex]
Divide 35 by 7 to get 5
[tex]m = 5[/tex]
