Answer:

x = 2

Step-by-step explanation:

[tex]\frac{x}{2x+1} = \frac{16}{40}[/tex]

Step 1: Cross multiply

We want to eliminate all denominators, so we multiply the opposite numerators and denominators

[tex]\frac{x}{2x+1} = \frac{16}{40}\\\\\\x\cdot40 = 16(2x + 1)\\\\\\40x = 32x + 16[/tex]

Step 2: Solve for x

Now we want x by itself, and we have to solve for x.

  • Move all terms with x on one side

             [tex]40x = 32x + 16\\\\\\40x - 32x = 16\\\\\\8x = 16[/tex]

  • Now remove all coefficients with x

             [tex]8x = 16\\\\8(x) = 16\\\\x = 16/8\\\\x = 2[/tex]

Answer:

x=2

Step-by-step explanation:

40*x=16(2x+1)  (we cross multiply)

40x=32x+16

8x=16

x=2
