Answer:

the notebook costs P25

the pen costs P18

Step-by-step explanation:

Let n represent the price of the notebook

     p represent the price of the pen

n + p = P43

n = p + P7

using substitution,

p + P7 + p = P43

2p = P43 - P 7

2p = P36

p = P18

n = P18 + P7

n = P25

n = P25, p = P18

∴, the price of the notebook is P25 and the price of the pen is P18

Note yung order po nila na price ng notebook una tapos price ng pen pangalawa kasi unang tinanong sa problem po yung price ng notebook tapos yung price ng pen. Mali na po kasi yun kung iuuna mo yung price ng pen isulat tapos panghuli lang yung notebook
