Answer:
x=4
Step-by-step explanation:
3x-5 = 7
Add 5 to each side
3x-5+5 = 7+5
3x = 12
Divide each side by 3
3x/3 = 12/3
x = 4
[ changing sides, changes addition to subtraction and subtraction to addition] [ multiplication changes to division and division changes to multiplication]
3x -5 =7
3x = 7 + 5
x = 12/3
