2y = 7x + 2

Answer:

The answer is $t\geq 20$ .

Step-by-step explanation:

To solve the inequality, start by solving for the variable $t$ .

To solve for the variable $t$ , subtract $3.5t$ from both sides. The inequality will look like $6.5t\geq 130$ .

Then, divide both sides by 6.5 in order to get the variable $t$ by itself. The inequality answer will look like $t\geq 20$ .
