Question 311488
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 = {{{t/10}}}
:
w + t = 495
replace w with t/10
{{{t/10}}} + t = 495 
multiply by 10
t + 10t = 4950
11t = 4950
t = {{{4950/11}}}
t = 450
check by finding w
w = {{{450/10}}} 
w = 45
:
45 + 450 = 495
