Answer:
X=1
Step-by-step explanation:
First lets combine like terms.
3=7x-4 (2x and 5x can be combined.)
Next, isolate your X variable.
7=7x (when you move a variable to the other side of the equation it gains the opposite sign Ex:-4 would become 4 and 4 would become -4)
Finally, find out what you need to multiply with x to get 7.
You need to multiply 1 with 7 to get 7.
The answer is x=1
