Question

solve the equation 5x - 1 = 19. the options are: x = 4, x = 5, x = 10, x = 15

Explanation:

Step1: Isolate the term with x

Add 1 to both sides of the equation.
$5x - 1 + 1 = 19 + 1$
$5x = 20$

Step2: Solve for x

Divide both sides by 5.
$\frac{5x}{5} = \frac{20}{5}$
$x = 4$

Answer:

$x = 4$
