Q. Is (3,1) a solution to this system of equations?3x+3y=1212x+y=13Choices:(A) yes(B) no
Check First Equation: We need to check if the point (3,1) satisfies the first equation:3x+3y=12Substitute x=3 and y=1 into the equation:3(3)+3(1)=129+3=1212=12The point (3,1) satisfies the first equation.
Check Second Equation: Now, we need to check if the point (3,1) satisfies the second equation:12x+y=13Substitute x=3 and y=1 into the equation:12(3)+1=1336+1=1337=13The point (3,1) does not satisfy the second equation.
