First write it out.
1/3x - 36 ≥ 22
Add 36 to both sides
1/3x ≥ 58
divide both sides by 1/3, and you get 174
1/3x - 36 ≥ 22
Add 36 to both sides
1/3x ≥ 58
divide both sides by 1/3, and you get 174
the number: x
one third of the number: [tex] \frac13x[/tex]
decreased 36: -36
at most means equal or less: ≤
So, we get: [tex]\frac13x-36\leq22[/tex]
add 36 to both sides: [tex]\frac13x-36+36\leq22+36[/tex]
[tex]\frac13x\leq58[/tex]
Multiply both sides by 3: [tex]3\cdot\frac13x\leq3\cdot58[/tex]
[tex]~\ \ \ x\leq 174\\\\ x\in(-\infty\ ;\ 174\ \textgreater[/tex]
