$2.5(6v-4)=10+4(1.5+0.5)\\\\(2.5)(6v) - 2.5(4)=10 + 4(1.5) + 4(0.5)\\\\15v - 10 = 10 + 6+2 \\\\15v - 10 = 18\\\\15v - 10 + 10 = 18 + 10\\\\15v = 18\\\\\frac{15v}{15} =\frac{18}{15} \\\\v = \frac{18}{15}\\\\v = \frac{6\times 3}{5\times 3}\\\\v=\frac{6}{5}\\\\\boxed{\bf{ v = \frac{6}{5} = 1\frac{1}{5}}}$

Complete question is;

Jackson has to repaint some classroom bookcases. He has 2 gallons of paint. All the bookcases are the same size and each requires 2/5 gallon of paint. How many bookcases is he able to repaint with the amount of paint?

Answer:

5 books

Step-by-step explanation:

Jackson has 2 gallons of paint

Now, for us to find the number of bookcases the Jackson will be able to repaint if each bookcase requires 2/5 gallon, we will just divide 2 by 2/5

Thus;

Number of book cases Jackson will be able to repaint = 2 ÷ 2/5

Thus gives; 2 × 5/2 = 5 books
