Answer:
x = 2
Step-by-step explanation:
[tex]\frac{x+1}{x+3}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5(x + 1) = 3(x + 3) ← distribute parenthesis on both sides
5x + 5 = 3x + 9 ( subtract 3x from both sides )
2x + 5 = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
