7TH GRADE MATH ASAP. Liam is setting up folding chairs for a meeting. If he arranges the chairs in 8 rows of the same length, he
has 11 chairs left over. If he arranges the chairs in 6 rows of that same length, he has 13 left over. How many chairs does Liam have?
1 answer:
Answer:
19 chairs
Step-by-step explanation:
you can make two equations
1. y = 8x + 11
2. y = 6x + 13
Y is the number of total chairs and x is the length
so 8x + 11 = 6x + 13
2x = 2
x = 1
so the length is one
To find the total number of chairs just plug in one as x
y = 8 + 11
y = 6 + 13
y = 19
so 19 chairs is the number of chairs Liam has.
