Answer:
There is one solution.
x = -17
<em>Proof and step-by-step explanation:</em>
Step 1: <em>Add the numbers</em>
3x-7 = 4+6+4x
3x-7 = 10+4x
Step 2: <em>Move</em><em> </em><em>terms</em>
3x-7 = 10+4x
3x-4x = 10+7
Step 3: <em>Collect the like terms and calculate the sum</em>
3x-4x = 10+7
-x = 17
Step 4: <em>Change the sign by multiplying both sides by -1</em>
-x (×-1) = 17 (×-1)
x = -17
I hope this helped ! :)
