NEED HELP ASAP solve for x : 3/5 = x-1/8 <br>a.5 b.29/5 c.23/5 d.19/5

Levart [38]

Answer:

<h3> $\boxed{ \sf{ \bold{ \huge{ \boxed{ \frac{29}{5} }}}}}$ </h3>

Option B is the correct option.

Step-by-step explanation:

$\sf{ \frac{3}{5} = \frac{x - 1}{8} }$

Apply cross product property

⇒ $\sf{ 5(x - 1) = 3 \times 8}$

Distribute 5 through the parentheses

⇒ $\sf{5x - 5 = 3 \times 8}$

Multiply the numbers

⇒ $\sf{5x - 5 = 24}$

Move 5 to right hand side and change it's sign

⇒ $\sf{5x = 24 + 5}$

Add the numbers

⇒ $\sf{5x = 29}$

Divide both sides of the equation by 5

⇒ $\sf{ \frac{5x}{5} = \frac{29}{5} }$

⇒ $\sf{x = \frac{29}{5} }$

Hope I helped!
