Q. How many solutions does this equation have?5w=4w−10Choices:(A)no solution(B)one solution(C)infinitely many solutions
Subtract 4w: Subtract 4w from both sides of the equation to isolate the variable w on one side.5w−4w=4w−4w−10w=−10
Check solution: Check the solution by substituting w=−10 back into the original equation.5(−10)=4(−10)−10−50=−40−10−50=−50The solution w=−10 satisfies the original equation.
