Solve the following pairs of equations for x and y: a²/x - b²/y = 0, a²b/x + b²a/y = a+b,

x≠0; y≠0

Solve the following pair of equations for x and y :

Given pair of equations are

and

On multiply equation (1) by a, we get

On adding equation (3) and (2), we get

On substituting the value of x in equation (1), we get

Consider the first equation

On substituting the values of x and y, we get

Hence, Verified

So, Solution of pair of equations is

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
