Answer:
<em>(8.21, -20.79)</em>
Step-by-step explanation:
Given the simultaneous equation;
From 2;
a = 29 + b ....3
Substitute 3 into 1;
Factorize
b = -18±√18²-4(-58)/2
b = -18±√324+232/2
b = -18±√556/2
b = -18±23.58/2
b = -18-23.58/2 and -18+23.58/2
b = -41.58/2 and 5.58/2
b = -20.79 and 2.79
Since a = 29 + b
when b = -20.79
a = 29 - 20.79
a = 8.21
<em>Hence the solution to the system of equation is (8.21, -20.79)</em>

Answer:
Reduced price = $ ( p - 150)
Step-by-step explanation:
Let the original price of plane ticket be $p
Price reduced in plane ticket = $150
So the amount actually need to pay for a plane ticket will be given by:
Actual reduced price of plane ticket = $p - $150
i.e Algebraic expression for reduced price is:
Reduced price = $ (p - 150)
