Now x = the first brother and y = second brother.
Their combined $x+y=55$
One brother has 15 more than the other. $x=y-15$
Let, solve the two equation together by substitute $\left(y-15\right)+y=55$. Place the values of x from the second equation
$y-15+y=55$
$2y-15=55$
$2y=55+15$ Move -15 to the order side
$2y=70$
$\frac{2y}{2}=\frac{70}{2}$ Divide by -4
$y=35$ and $x=35-15=20$ One of the two brother has 35 and the other has 20
