Question

if m over 3 minus m - 1 over 2 =1,then m =....... help

Answer 1

m/3 - m - 1/2 = 1
multiply everything by 6:
6m/3 - 6m - 6/2 = 6
simplify:
2m - 6m - 3 = 6
add 3 to both sides:
2m - 6m - 3 + 3 = 6 + 3
simplify:
-4m = 9
divide both sides by -4:
-4m/-4 = 9/-4
simplify:
m = -9/4

Answer 2

i mean m minus 1 divide by 2

Answer 3

m/3 - (m-1)/2 = 1
multiply everything by 6:
6m/3 - 6(m-1)/2 = 6
simplify:
2m - 3(m-1) = 6
open up the parenthesis:
2m - 3m + 3 = 6
subtract 3 from both sides:
2m-3m+3-3=6-3
simplify:
-m = 3
multiply both sides by -1:
m = -3

Answer 4

ok thanks sorry for the mistakes

Answer 5

can i ask somethin ...why the (m-1) become 3m+3

Answer 6
