# How do you solve the inequality 7²=<6-y?

Dec 29, 2015

First step is to work out the square

#### Explanation:

$\to 49 = < 6 - y$

You may add or subtract on both sides equally, so we add $y$
$\to 49 + y = < 6 - \cancel{y} + \cancel{y}$

Then subtract $49$ on both sides:
$\to \cancel{49} - \cancel{49} + y = < 6 - 49$
$\to y = < - 43$
