OK
So 3x = x+78
3x-x = 78
2x = 78
x = 39
Do I get a prize?

It relies upon the position the brackets are.. do you advise "3 situations, a wide determination +8" or do you advise "3 situations a wide determination, +8"? enable x = the wide type "3 situations a wide determination, +8" (3x) + 8 = x - a million 2x = -9 x= -9/2 x= -4.5 ------------------- "3 situations, a wide determination +8" 3(x+8) = x - a million 3x+24 = x - a million 2x = -25 x = -25/2 x = -12.5

I don't know how you can do your example and not this one.
3*x = x + 78, so subtract x from both sides to get:
2*x = 78, so:
x = 39.

so,
3*n = n+78
solve for n

3x = x + 78
2x = 78
x = 39
The number is 39
-----------------------------
n + 24 = 31
n = 7
The number is 7
