Answer:
16 pencils and 17 glue sticks
Step-by-step explanation:
X=pencils
Y=glue sticks
X+Y=33
1.50X+2Y=58

=15X+20Y=580
same for e1
=10X+10Y=330
15X+20Y=580
10X+10Y=330
elimination mthd
150X+200Y=5800
150X+150Y=4950
50Y= 850
<u>Y</u><u>=</u><u>1</u><u>7</u>
<u>X</u><u>+</u><u>17</u><u>=</u><u>3</u><u>3</u>
X=33-17
X=16
