Question

Solve for x :
(3/x) = (7/x+1)

Answer 1

Answer:

$\frac{3}{x} = \frac{7}{x + 1}$

3(x+1) = 7x

3x + 3 = 7x

4x = 3

$x = \frac{3}{4}$

Answer 2

Answer:

$\\\\\\\\3\left(x+1\right)=x\cdot \:73x+3=x\cdot \:73x+3-3=x\cdot \:7-33x-x\cdot \:7=x\cdot \:7- 3-x\cdot \:73x-x\cdot \:7=x\cdot \:7-3-x\cdot \:73x=x\cdot \:7-3-4x/-4=-3/-4x=3/4$
