Q. 4y3x=40 4 y-3 x=40 \newline4y=3x30 4 y=3 x-30 \newlineWhich of the following accurately describes all solutions to the system of equations shown?\newlineChoose 11 answer:\newline(A) x=0 x=0 and y=0 y=0 \newline(B) x=53 x=\frac{5}{3} and y=454 y=\frac{45}{4} \newline(C) There are infinite solutions to the system.\newlineD There are no solutions to the system.
  1. Analyze the equations: Analyze the given system of equations.\newlineWe have two equations:\newline11. 4y3x=404y - 3x = 40\newline22. 4y=3x304y = 3x - 30\newlineWe need to determine the relationship between these two equations to find the solution set.
  2. Compare the equations: Compare the two equations.\newlineBy looking at the two equations, we can see that they are not identical. To better understand their relationship, we should try to express both equations in terms of one variable, for example, yy.
  3. Express first equation in terms of y: Express the first equation in terms of y.\newlineFrom the first equation, we can solve for y:\newline4y3x=404y - 3x = 40\newline4y=3x+404y = 3x + 40\newliney=3x+404y = \frac{3x + 40}{4}
  4. Express second equation in terms of y: Express the second equation in terms of y.\newlineThe second equation is already solved for y:\newline4y=3x304y = 3x - 30\newliney=3x304y = \frac{3x - 30}{4}
  5. Compare expressions for yy: Compare the expressions for yy from both equations.\newlineWe have:\newlineFrom equation 11: y=3x+404y = \frac{3x + 40}{4}\newlineFrom equation 22: y=3x304y = \frac{3x - 30}{4}\newlineThese two expressions cannot be equal for any value of xx because they differ by a constant term (4040 vs. 30-30). Therefore, there is no value of xx that will satisfy both equations simultaneously.
  6. Conclude the number of solutions: Conclude the number of solutions.\newlineSince there is no value of xx that satisfies both equations, the system of equations has no solutions.
