Question 1153850
<br>
{{{5a+2c = 128}}}
{{{3a+4c = 116}}}<br>
I will describe in words what I would do to solve this pair of equations; you can do the work to find the solution.<br>
(1) double the first equation to find the cost of 10 adult tickets and 4 children's tickets.
(2) compare that to the second equation (algebraically, subtract one equation from the other) to find the cost of 7 adult tickets.
(3) use that result to find the cost of one adult ticket.
(4) use the cost of each adult ticket in either of the original equations to determine the cost of each children's ticket.<br>
