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