The equation 5x+8-7x=-4x+1 has exactly one solution
Option B is correct
The given equation is:
5x + 8 - 7x = -4x + 1
Simplify both sides of the equation
5x - 7x + 8 = -4x + 1
-2x + 8 = -4x + 1
Collect like terms
-2x + 4x = 1 - 8
2x = -7
Divide both sides by 2
[tex]\frac{2x}{2} =\frac{-7}{2} \\\\x=-3.5[/tex]
As seen above, the equation has exactly one solution
