Q. x+4y=4 -x+4 y=4 \newlinex+3y=1 -x+3 y=1 \newlineIs (8,3) (8,3) a solution of the system?\newlineChoose 11 answer:\newline(A) Yes\newline(B) No
  1. Check First Equation: First, let's check if the point (8,3)(8,3) satisfies the first equation: x+4y=4-x + 4y = 4. Substitute x=8x = 8 and y=3y = 3 into the equation: 8+4(3)=8+12=4-8 + 4(3) = -8 + 12 = 4. Since the left side equals the right side, the point satisfies the first equation.
  2. Check Second Equation: Now, let's check if the point (8,3)(8,3) satisfies the second equation: x+3y=1-x + 3y = 1. Substitute x=8x = 8 and y=3y = 3 into the equation: 8+3(3)=8+9=1-8 + 3(3) = -8 + 9 = 1. Since the left side equals the right side, the point satisfies the second equation as well.
