Ответ:
x= 2.5
Step-by-step explanation:
7x-5x = 2x
2x-2 = 3
3 + 2 = 5
2x=5
5/2 = 2.5
Ответ:
5/2 or 2.5
Step-by-step explanation:
So first you add 2 to -2( crossing it out) and add 2 to 3. Then you simplify giving you the equation of 7x=5x+5.
Then subtract 5x from 7x and 5 giving you the equation of 2x=5.
Ounce done divide your equation by 2, giving you the answer if 5/2 or 2.5.
