Tickets for section A cost \$a each
Tickets for Section B cost \$b each

Johanna paid \$105 for 5 section A tickets and 3 section B tickets.
Raiyah Paid \$63 for 4 section A tickets and 1 section B ticket

Write 2 equations in a and b to represent the info.
1)5a+3b=105
2)4a+b=63
Is this correct?
And how do i calculate the values of a and b?

1. The equations are correct.

To solve, I would multiply both sides of the second equation by 3, then subtract equation 2 from 1. The b terms will have subtracted out.
