Q. How many solutions does the following equation have?\newline5x+87x=4x+15x+8-7x=-4x+1\newlineChoose 11 answer:\newline(A) No solutions\newline(B) Exactly one solution\newline(C) Infinitely many solutions
  1. Combine like terms: Combine like terms on the left side of the equation.\newline5x7x+8=4x+15x - 7x + 8 = -4x + 1\newlineThis simplifies to:\newline2x+8=4x+1-2x + 8 = -4x + 1
  2. Add xx terms together: Add 4x4x to both sides to get all the xx terms on one side.\newline2x+4x+8=4x+4x+1-2x + 4x + 8 = -4x + 4x + 1\newlineThis simplifies to:\newline2x+8=12x + 8 = 1
  3. Isolate x term: Subtract 88 from both sides to isolate the term with xx.\newline2x+88=182x + 8 - 8 = 1 - 8\newlineThis simplifies to:\newline2x=72x = -7
  4. Solve for x: Divide both sides by 22 to solve for x.\newline2x2=72\frac{2x}{2} = \frac{-7}{2}\newlineThis simplifies to:\newlinex=72x = \frac{-7}{2}
  5. Final solution: Since we have found a value for xx, the equation has exactly one solution.
