William and amy are stuffing envelopes for a charity. today William stuffed a total of 70 envelopes. this was 10 more than twice the number of envelopes that amy stuffed. how many envelopes did amy stuff?

Sagot :

the number of envelopes Amy stuffed = x
twice the number of envelopes Amy stuffed = 2x
10 more than twice the number of envelopes Amy stuffed = 2x+10

[tex]2x+10=70 \\ 2x=70-10 \\ 2x=60 \\ x=30[/tex]

Amy stuffed 30 envelopes.
william stuffed 70
W=70
this was 10 more than (+10) twice the number of envelopes (2a) amy stuffed
W=10+2A
find A
W=70
70=10+2A
subtract 10 from both sides
60=2A
divide both sides by 2
30=A
amy stuffed 30 envelopes
