8/m-9=6/m-8
what does m equal?
show clear steps!

8/m-9=6/m-8

Move -9 to the other side. Sign changes from -9 to +9.

8/m-9+9=6/m-8+9

8/m=6/m+1

Move +6m to the other side. Sign changes from +6m to -6m.

8/m-6/m=6/m-6/m+1

2m could also equal to : 1/2m

1/2m=1

Multiply by 2/1 for 1/2m and 1.

1/2(2/1)m=2/1(1)

Cross out 2 and 2, divide by 2. Cross out 1 and 1, divide by 1.

m=2

m=2

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
