Answer: 456 chairs
Step-by-step explanation:
If there are 6 round tables with 7 chairs each you would multiply 7, 6 times (7 x 6) = 42
If there are 23 rectangular tables with 18 chairs each you would multiply 18, 23 times. ( 18 x 23) = 414

Step-by-step explanation:
multipy both equations by 12
9x+60=10
then move the constant to the right hand side and change it's sign
9x= 10 - 60
calculate difference
9x = -50
divide both sides by 9
x= - 50/9
