Answer:
F = -16
Step-by-step explanation:
F/4-5=-9
Add 5 to each side
F/4-5+5=-9+5
F/4=-4
Multiply each side by 4
F/4 *4=-4*4
F = -16
Answer:
w=57
Step-by-step explanation:
The angles are supplementary because they are adjacent to one another and lies on a straight line
w-8+2w-1=180
Combine like terms
3w-9=180
Subtract 9 on both sides
3w=171
Divide 3 on both sides
w=57
Answer:

Step-by-step explanation:
Isolate the variable, do this by first multiplying both sides by two


Subtract 2x from both sides of the equation

Add one to both sides of the equation

Divide both sides by 2
