Answer:
no solution
Explanation:
0.5 ( -2 + 4d ) - 2d = -13
Solve the brackets.
-1 + 2d - 2d = -13
The term "-2d" cancels out, leaving us with:
-1 = -13
Since this equation is not true (the left side does not equal the right side), there is no solution to the equation.
In other words, there is no value of "d" that satisfies the equation.
