Solve the following equations -
a1 = 3.5, b1 = 9.5, a2 =4.5 and b2 = 3.5
a1 + a2 = 8 and a2 + b2 = 8. So a1 + a2 = a2 + b2 which gives a1 = b2.
Now take b1 - b2 = 6 and using a1 = b2 we get b1 - a1 = 6.
we have a1 + b1 = 13, So adding these two equations we get 2b1 = 19, So b1 = 9.5
It is easy to get remaining values from the remaining equations.
Let a1 and a2 be the roots or the equation (x- a)(x - b) = c and c != 0, then what are the roots of the equation (x - a1)(x - a2) + c = 0?
Can you solve the equations and find the value of the missing number?
