Mr. and Mrs. Hernandez own a laundry shop. They had 134 customers this week. This is 18 fewer than last week since it is pandemic. Write an algebraic equation for the number of customers they had last week. Let c be the number of customers they had last week.

[tex]\sf\blue{Step-by-step \: explanation}[/tex]

18 fewer than the number of customers lost week is 134

[tex] \: \: \: \: \: \: \: \: \: \: c - 18 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 134[/tex]

Algebraic Equation: [tex] c - 18 = 134 [/tex]

[tex] \: \: c - 18 = 134 \\ c - 18 + 18 = 134 + 18 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: c = 116[/tex]

  • Adding the additive inverse of -18, is adding 18 on both sides to cancel out -18. Since -18 + 18 = 0

Therefore they had 116 customer last week.
