Question

lochana · Answer

$$\frac{x+20}{2}$$

jazzyluvsu123 · Answer

x+202=3x

2(x+202)=3x(2)
    This cancels out the 2 in the fraction
x+20=6x

 -x         -x
      20 = 5x
       /5   /5
        x = 4

x+20=3x

jazzyluvsu123 · Answer

$$2(x+20)=3x(2)     This cancels out the 2 \in the fraction x+20=6x   -x         -x       20 = 5x        /5   /5         x = 4$$

jazzyluvsu123 · Answer

Here - x + 20/2 = 3x 
multiple both sides by 2 to get rid of the 2 
2(x+20/2) = 3x(2) 
the 2s cancel each other out on the left side 
x+20=6x 
you want to get the x's on the same side 
so subtract x from each side 
20=5x 
divide both sides by 5 to get x on its own 
20/5 = 5x/5 
4=x
