$\frac{4x}{5} - 1 = 7 \\ \\ \frac{4x}{5} = 7 + 1 \\ \\ \frac{4x}{5} = 8 \\ \\ 4x = 8 \times 5 \\ \\ 4x = 40 \\ \\ x = \frac{40}{4} \\ \\ x = 10$

Answer 2

Answer:

$x= 10$

Step-by-step explanation:

$\frac{4x}{5} - 1 = 7 \\ \frac{4x - 5}{5} = 7 \\ 4x - 5 = 7 \times 5 \\ 4x - 5 = 35 \\ 4x = 35 + 5 \\ 4x = 40 \\ x = \frac{40}{4} \\ x= 10 \\ option \: a$
