Q. Is the point (1,3) a solution of the system of equations below? Justify.y=4x−12x+2y=8
Substitute Point into First Equation: Substitute the point (1,3) into the first equation y=4x−1.Calculation: y=4(1)−1=4−1=3.
Check Y-Value Match: Check if the calculated y-value matches the y-coordinate of the point.Calculation: The y-coordinate of the point is 3, which matches the calculated y-value.
Substitute Point into Second Equation: Substitute the point (1,3) into the second equation 2x+2y=8.Calculation: 2(1)+2(3)=2+6=8.
Check Sum Match: Check if the calculated sum matches the right side of the equation.Calculation: The sum is 8, which matches the right side of the equation.
