# How do you solve and write the following in interval notation: -4 ≤ 3 - y ?

$y \le 7$. In interval notation the solution is $\left(- \infty , 7\right]$
$- 4 \le 3 - y \mathmr{and} - 7 \le - y \mathmr{and} 7 \ge y \mathmr{and} y \le 7$. In interval notation
the solution is $\left(- \infty , 7\right]$[Ans]
