15. 2x-5=-20
2x=-15; Add positive 5 on both sides to isolate x.
x=; Divide 2 on both sides to find the value of x.
17. =-9
9x=-36; Multiply positive 4 on both sides of the equation.
x==-4; Divide 9 on both sides of the equation to find the value of x.

Answer:
No solution
Step-by-step explanation:
Create an equation with the values given. Solve like an algebraic question.
11 > 3*x = 75> -1*x
3*x and -1*x should lead to a value greater than 11.
Since there is no value that can be multiplied by a negative and be a positive, besides negative numbers, in which the term of 11>3*x wouldn't be positive, this would have no solution.
No solution.
