12-5x= 7x+3
12-7x-5x= 7x-7x+3
12-12x= 3
12-12-12x= 3-12
-12x= -9
Divide by -12 for -12x and -9
-12x/-12= -9/-12
x= 9/12
Divide by 3 for 9/12
x= 3/4
Answer is x= 3/4
Step-by-step explanation:
12 - 5x = 7x + 3
Add 5x on the both sides so there would only be 12 on the right side.
So...... 12 = 12x + 3
Then minus 3 from both sides
9 = 12x
0.75 = x
