Answer:

x=3

Step-by-step explanation:

[tex]45-\frac{90}{x} = 15[/tex]

Minus 45 from both sides

[tex]-\frac{90}{x}=-30[/tex]

Multiply both sides x

[tex]-90=-30x[/tex]

Divide both sides by -30

[tex]3=x[/tex]

Answer:

3

Step-by-step explanation:

To eliminate the x on the denominator, multiply all terms by x

45x - 90 = 15x ( subtract 45x from both sides )

- 90 = - 30x ( divide both sides by - 30 )

3 = x ⇒ x = 3
