Well if she had 37 more pencils than pens and we know she had 56 pens we add 37 to 56 to find out how many pencils she had.
37+56=93. She had 93 pencils.
Then to find out how many pencils and pens she had we add the number of pencils and pens she had.
56+93=149. She had 149 pencils and pens.
System of equations:
y = 6x + 104
y = 10x + 60
Method : <span>Substitution
Since the both equation is equal to y, you can substitute one equation for the other equation's y:
</span>
y = 6x + 104
10x + 60 = 6x + 104
-6x -60 =-6x -60
