Q. How many solutions does this equation have?\newline5w=4w105w = 4w - 10\newlineChoices:\newline(A)no solution\newline(B)one solution\newline(C)infinitely many solutions
  1. Subtract 4w4w: Subtract 4w4w from both sides of the equation to isolate the variable ww on one side.\newline5w4w=4w4w105w - 4w = 4w - 4w - 10\newlinew=10w = -10
  2. Check solution: Check the solution by substituting w=10w = -10 back into the original equation.5(10)=4(10)105(-10) = 4(-10) - 1050=4010-50 = -40 - 1050=50-50 = -50The solution w=10w = -10 satisfies the original equation.
