The sum of three times the smaller number and bigger number is 51. The bigger number is two more than four times the smaller. Find the numbers.
small no.= x
larger no.= y
three times the sum of two numbers in 51
3(x+y)=51 -------equ 1
the larger number is plus four twice the smaller number.
y=2x+4 -------equ 2
substitute y=2x+4
3(x+2x+4)=51
3(3x+4)=51
9x+12=51
9x=39
x=4.33
y=12.67
