x=2/3y
x+y=175
substitute the first into the second: 5/3y=175 y=105, x=70.

let the first number be x
let the second number be y
one number is 2/3 of other number
x = 2/3 * y ---->eq(1)
sum of the two numbers is 175
x + y = 175
x = 175 - y ----- eq(2)
putting this in eq(1)
x = 2/3 * y
175 - y = 2/3 * y
175 = 2/3 * y + y
175 = y * ( 1 + 2/3)
175 = y(5/3)
y = 175 * 3/5 = 105
y = 105
x = 175 - y = 175 - 105 = 70
x = 70
therefore, we have
x = 70
y = 105
greatest number is y, which is 105
hope this helps

x = (2/3)y
x + y = 175
(2/3)y + y = 175
(5/3)y = 175
5y = 525
y = 105
x = (2/3)(105)
x = (210/3)
x = 70
the numbers are 70 and 105

105 and 70.
5/3 x = 175
5x= 525
x=105
2/3 x= 70

LET THE NOS. BE: 3X & 2X
SO THEIR SUM = 3X + 2X = 5X = 175
SO, X = 35
SO THE GREATEST NO. = 3X = 35*3 = 105

x+(2/3)x=175
5/3x=175
x=105
the greater no is 105
