PEMDAS: distribute the negative to (-2-5x) so it becomes (2+5x)+(-2)=18
Add 2 to both sides: 2+5x=20
Subtract 2: 5x=18
Divide 5: x= 18/5
Answer:

Step-by-step explanation:
Answer:
20
Step-by-step explanation:
the inverse of
y=1/2x + 10
is
x=1/2y+10
from here you just solve for y
x-10 = 1/2y
2(x-10) = y
2x-20 = y
Your answer would be “a”.
In order to receive a positive solution in the following equation, you must include a double negative to have them cancel each other out and come up with a positive value. Sorry if this is confusing it’s easier to explain this process in person rather than online but I hope this helps anyways :)
