X=-11
combine like terms (-9x and 7x) then (-4 and -8) then you have -2x-12=10 so you add 12 and 10 and you have -2x=22 lastly you divide and get x=-11

Answer:

$m=3$

Step-by-step explanation:

$6m+5-3m=7(m-1)$

Combine like terms

$3m+5=7(m-1)$

Distribute the 7

$3m+5=7m-7$

Subtract 3m from each side

$4m-7=5$

Add 7 to each side

$4m=12$

Divide by 4

$m=3$
