Answer:

x = 2

Explanation:


(x)/(2x+1) = (16)/(40)

Step 1: Cross multiply

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


(x)/(2x+1) = (16)/(40)\\\\\\x\cdot40 = 16(2x + 1)\\\\\\40x = 32x + 16

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


40x = 32x + 16\\\\\\40x - 32x = 16\\\\\\8x = 16

  • Now remove all coefficients with x


8x = 16\\\\8(x) = 16\\\\x = 16/8\\\\x = 2
