This is doing my head in and until I get it solved I can’t go out for a ride.

Apparently the answer to the following equation is 0.04, but how?

0.1d = 2.5(1+d)x -0.1

Is that an x or a multiply?

is that a letter x or a multiplication sign?

assuming it’s an x, they cancel out and i got d=-1…

Oops sorry it is a letter X and I’m trying to solve for X

If multiplication..

Cancel out the 0.1

d = -2.5(1+d)
d = -2.5 -2.5d
3.5d = -2.5
d = -2.5/3.5 = -0.714285714…

If x..

0.1d = 2.5(1+d)x -0.1
(0.1d + 0.1)/(1 + d) = 2.5x
0.1(1 + d)/(1 + d) = 2.5x
0.1/2.5 = x = 0.04

Don’t think of me as a hero.

I concur.

yes I agree withboy realman maths student as well just wish I knew what any of it meant

d is a variable in this, x is a constant – possibly why it’s throwing people off, it’s a little odd.

no honestly it is my maths ability despite an A in O level in 1986 I am poor at “proper” maths forgotten almost everything.

Me too. 😳

Oh thank god for that. Realman you are my hero (and Sophie’s)

That’s it I’m off out to enjoy this sun

Thanks again fella!
