You can put this solution on YOUR website! the sum of the integers t and w is 495.
w + t = 495
the units digit of t is 0, if t is divided by 10, the result is equal to w.
what is the value of t?
:
"if t is divided by 10, the result is equal to w"
w =
:
w + t = 495
replace w with t/10 + t = 495
multiply by 10
t + 10t = 4950
11t = 4950
t =
t = 450
check by finding w
w =
w = 45
:
45 + 450 = 495
