Let the price of 1 chair be $x
then the price of 1 table = x + 50
cost of 5 table + 2 chair = 990
5 (x + 30) + 2 (x) = 990
5x + 150 + 2x = 990
7x = 840
x = 840รท 7
x=120
Cost of a chair=$120
Cost of a table=$(120 + 30)
=$150
then the price of 1 table = x + 50
cost of 5 table + 2 chair = 990
5 (x + 30) + 2 (x) = 990
5x + 150 + 2x = 990
7x = 840
x = 840รท 7
x=120
Cost of a chair=$120
Cost of a table=$(120 + 30)
=$150
