Thread: solving these similtaneous eqns with unknown constants

how do i solve:

a - b = 0.2c
a = 2d
a + 0.5b = 2e

i need to find values for c, d and e as an end point

You have to solve these equations for c, d, and e in terms of a and b? You basically have that already. What exactly are you supposed to do for this?

need c, d, and e in integer form ie as numbers. so guess have to solve for a & b first?

In order to have each variable equated to an integer, you must have as many equations as unknowns.

Right now, you have three equations involving five unknowns so you will have to have the result as an equation involving some variables.
