Question 1019852
Hi there,
make 2 person tables = 'x'
and 4 person tables = 'y'
x + y = 16.......(1)
2x + 4y = 50.....(2)
Multiply (1) by 2
2x + 2y = 32.....(1)
2x + 4y = 50.....(2)
Subtract (1) from (2)
.....2y = 18
......y = 9
Substitute y = 9 into (10
x + y = 16.......(10
x + 9 = 16
x = 16 - 9
x = 7
7 two person tables
9 four person tables.
Hope this helps :-)
