[tex]34x + 14 = 30x + 22[/tex]
X is the amount the multiple choice question is worth. Both girls had the same test score so both are equal. Isolate X and that will be the value.
[tex]34x -( 30x) + 14 = 22[/tex]
[tex]4x = 22 - (14)[/tex]
[tex]4x = 8[/tex]
[tex]4x \div 4 = 8 \div 4[/tex]
x = 2
Plug 2 back in for x in the original equation to check and both girls recieved a 82%
