Step-by-step explanation:

Let

x -----> the number

we know that

Three-eighths multiplied by a number plus one must be equal to 11

The linear equation that represent this situation is

$\frac{3}{8}x+1=11$

Solve for x

Subtract 1 both sides

$\frac{3}{8}x+1-1=11-1$

$\frac{3}{8}x=10$

Multiply by 8/3 both sides

$\frac{3}{8}x(\frac{8}{3})=10(\frac{8}{3})$

$x=\frac{80}{3}$

The number is 80/3
