How do you solve 5v-4 over 10 equals 4/5
First you multiply each side by 10. Your new equation is: 5v-4 = 40/5. This simplifies to 5v-4=8.
Next, you add four to each side, getting 5v = 8+4 or 5v = 12.
Finally, you divide each side by 5. The answer is: v = 12/5
Next, you add four to each side, getting 5v = 8+4 or 5v = 12.
Finally, you divide each side by 5. The answer is: v = 12/5

Since the 3 is outside of the parentheses you would have to distribute it. This means that you multiply x by 3, then you multiply 4 by three to get 3(x) + 3(4). SO 3 time x equals 3x plus 3 time 4 equals 12
This would give you 3x+12
