Respuesta :
3x+25=7x-5 subtract 25 from both sides
3x=7x-30 subtract 7x from both sides
-4x=-30 divide both sides by -4
x=7.5
3x=7x-30 subtract 7x from both sides
-4x=-30 divide both sides by -4
x=7.5
Answer:
x = 7.5.
Step-by-step explanation:
Given : Given the equation 3x + 25 = 7x − 5,
To find : which order of operations completely solves for x.
Solution : We have given that
3x + 25 = 7x − 5.
Subtracting both side by 3x
25 = 7x - 3x -5.
25 = 4x -5.
On adding both side by 5
25 +5 = 4x .
30 = 4x
on dividing by 4 both side.
x = 7.5.
Therefore, x = 7.5.
