Multiply both sides by 12q.

Get all values of q onto one side (ie +1.5q to both sides)

Subtract 16 2/3 from both sides to get all numbers onto the opposite side to q.

Divide both sides by the coefficient of q (ie 2.5)

You should have q = 1120 in front of you, if that's correct.

1/8q + 250 = 1/12q + 16 2/3
250 = 1/12q+16(2/3)-8q
250-12q = 32/3-8Q
250..................................... errrrr cant image more steps

-1/8q + 250 = 1/12q + 16 2/3

-1/8q -1/12q = 16(2/3) -250

-1/8q -1/12q = 32/3 -250

(-3 -2)/24q = (32-750)/3

-5/24q = -718/3

multiplying both sides by -1

5/24q = 718/3

5 x 3 = 718 x 24q

15 = 718 x 24q
15/718 = 24q
0.0208 =24q
.........looks like something is wrong in my calculations....It is hard to do on a laptop. I should have solved on a paper

I did excatly the same as you, and got the same answer.

Then I gave up the challenge, and decided to find it here.

The problem as I see it was the OP mentioning -1/8q incorrcectly
-1/8q should have been -q/8

Just for clarity included a lot of steps. but this can be simplified further easily.

-1/8 q + 250 = 1/12q + 16 2/3

-1/8 q = 1/12q + 50/3 - 250

-1/8q = 1/12q + 50/3 - 250

-1/8q = 1/12q + 50 - 750 / 3

-1/8 q - 1/12 q = - 700/3

(-1/8 - 1/12) q = - 700/3

(-12-8/12*8) q = - 700/3

(-20/96)q = -700/3

-20q = -700/3 * 96

-20q = - 67200/3

-20q = 22400

-q = - 22400/-20

-q = -1120

q = 1120

if "16 2/3" means 16 multiplied by 2 thirds, then you got the first step of this is wrong, as 16 * 2/3 is not 50/3.
