Answer:
x = 1
Step-by-step explanation:
5 x (2x - 8) + 15 = -15 Multiply 5 by 2x and -8
10x - 40 + 15 = -15 Add -40 and 15
10x - 25 = -15 Add 25 to both sides
10x = 10 Divide 10 by 10
x = 1

Answer:
Larry places 19 puzzles
Step-by-step explanation:
Step one:
given data
let the number of puzzles Larry places be x
and let the number of puzzles Drew places be y
so
y=3x-11
Step two:
We are told that Drew places at least 10
so for x= 10
y= 3*10-11
y=30-11
y=19
