7(2x+5)=4x-9-x
14x+35=3x-9
11x = -44
x = -4
7(2*-4+5)=4*-4-9--4
7(-3)=-21
-21=-21. so it checks out and x = -4

The missing factor is 20. 10 x 20 = 200
Answer:
x = -7
Step-by-step explanation:
4x - 9 = 7x + 12
~Add 9 to both sides
4x = 7x + 21
~Subtract 7x to both sides
-3x = 21
~Divide -3 to both sides
x = -7
Best of Luck!
