Question

Using the digits 0-9, no more than one time each, place a digit in a box to create an equation with a solution x= -1/2

Answer 1

Answer:

The required equation is 4x + 1 = 2x + 0

Step-by-step explanation:

- x + - = - x + -

Let

ax + b = cx + d

ax - cx = d - b

x (a - c) = d - b

x = d - b / a - c

since we want an equation whose solution is x = -1/2

Therefore,

-1/2 =  d - b / a - c

Choosing a,b,c,d from digits 0 - 9 not more than one time each

hence, we choose

d = 0

b = 1

a = 4

c = 2

The required equation is 4x + 1 = 2x + 0
