Given that the value of X in the solution of the system of quadratic equations 2x-5y + 3 = 0 and ax + y = 7 is 1, find the value of A
Take x = 1 into the first equation to get y = 1, and take x = 1, y = 1 into the second equation to get a = 6
Take x = 1 into the first equation to get y = 1, and take x = 1, y = 1 into the second equation to get a = 6
