Question

y= 3/8 (x+4) SOLVE FOR X

Please show your work. I'm really confused about this.

Answer 1

$\dfrac{3}{8}(x+4)=y\ \ \ \ |\text{multiply both sides by 8}\\\\3(x+4)=8y\ \ \ \ |\text{use distributive property}\\\\(3)(x)+(3)(4)=8y\\\\3x+12=8y\ \ \ \ |\text{substract 12 from both sides}\\\\3x=8y-12\ \ \ \ |\text{divide both sides by 3}\\\\\boxed{x=\dfrac{8y-12}{3}\to y=\dfrac{8}{3}y-4}$

Answer 2

Hi,

Let's solve for x.

y=  3 /8  (x+4)

Step 1: Flip the equation.

3/8x +3/2  =y

Step 2: Add (-3)/2 to both sides.

3/8x +  3/2+  −3/2  =y+  −3/2 3/8  x = y+  −3/2

Step 3: Divide both sides by 3/8.

3/8x  / 3/8 =   y+  −3/2/3/8

x= 8y−12/3

Answer:

x=  8y−12/3

Have a great day!
