[ Answer ]
[ Explanation ]
3x - 7 = 4 + 6 + 4x
Solve Equation To Find Out How Many Solutions Are Possible:
Add Numbers: 4 + 6 = 10
3x - 7 = 4x + 10
Add 7 To Both Sides:
3x - 7 + 7 = 4x + 10 + 7
Simplify:
3x = 4x + 17
Subtract 4x From Both Sides:
3x - 4x = 4x + 17 - 4x
Simplify:
-x = 17
Divide Both Sides By -1:
=
Simplify:
X = -17
We Have One Solution, And One Solution Only. Therefore, There Is One Solution To The Equation.
