Question 684059
52 - y + 4
...
{{{56-y - ((1/3)(56-y)) + 3 = 25}}}
...

{{{56-y - 56/3 + y/3 + 3 = 25}}}
{{{59 - y - 56/3 + y/3 = 25}}}
Multiply the entire equation by 3
177 - 3y - 56 + y = 75
177 - 2y - 56 = 75
121 - 2y = 75
-2y = 75 - 121
-2y = -46
{{{highlight_green(y = 23)}}}
...
Check
52-23+4 = 33
{{{(1/3)(33) = 11}}}
33 - 11  + 3= 25
Correct!
