Define an operation "*" in the range of rational number, the rule is a * b = a + B / 2, try to find the solution of equation 3 * (2 * x) = 1

Define an operation "*" in the range of rational number, the rule is a * b = a + B / 2, try to find the solution of equation 3 * (2 * x) = 1

a*b=a+b/2
Then 2 * x = (2 + x) / 2 = 1 + 0.5x
3*(2*x)=(3+1+0.5x)/2=1
3+1+0.5x=2
0.5x=-2
x=-4
