Answer: The required solution of the given inequality is
y\geq -4.

Step-by-step explanation: We are given to solve the following inequality :


7y-3\leq10y+9~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To solve the given inequality, we must find the value of the unknown variable p.

We will be using the following property of inequalities :


a\leq b~~~~~\Rightarrow -a\geq -b.

From inequality (i), we have


7y-3\leq10y+9\\\\\Rightarrow 7y-10y\leq9+3\\\\\Rightarrow -3y\leq12\\\\\Rightarrow 3y\geq -12\\\\\Rightarrow y\geq(-12)/(3)\\\\\Rightarrow y\geq -4.

Thus, the required solution of the given inequality is
y\geq -4.
