Question

Solve the equation for the indicated variable.
1. y= 3/8 (x+4) for x​

Answer 1

Answer:

x=8y/3-4

Step-by-step explanation:

What we have to do to solve for X into re arrange the equation so that X is by itself on one side of the equation.  To start we will divide both sides by 3/8 to move it away from the X side and we get

8y/3=x+4 then we will subtract both sides by 4 to get x all by itself

8y/3-4=x

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Answer 2

Answer:

$\large\boxed{x=\dfrac{8}{3}y-4}$

Step-by-step explanation:

$\dfrac{3}{8}(x+4)=y\qquad\text{multiply both sides by 8}\\\\8\!\!\!\!\diagup^1\cdot\dfrac{3}{8\!\!\!\!\diagup_1}(x+4)=8y\\\\3(x+4)=8y\qquad\text{divide both sides by 3}\\\\\dfrac{3(x+4)}{3}=\dfrac{8y}{3}\\\\x+4=\dfrac{8}{3}y\qquad\text{subtract 4 from both sides}\\\\x=\dfrac{8}{3}y-4$
