Question 861243
L = 8 dollars/ticket
H = 12.50 dollars/ticket
x = how many low price tickets
y = how many high price tickets


Account for tickets:  x+y=244
Account for revenue (total money of sales): Lx+Hy=2267


The variables needing be solved are x and y.  A suggestion for method is to use Substitution.


Starting that process,
{{{y=244-x}}}.
{{{Lx+H(244-x)=2267}}}
{{{Lx+244H-Hx=2267}}}
{{{Lx-Hx=2267-244H}}}
.
.
