Answer:
The solutions to the equation are x = 5 and x = 3, or f and e.
Step-by-step explanation:
Solutions to the equation can also be said as the zeros of the equation.
To find the zeros of the equation, set both parts of the equation equal to 0.
x - 5 = 0
Add 5 to both sides.
x = 5
AND
7x - 21 = 0
Add 21 to both sides.
7x = 21
Divide both sides by 7.
x = 3
