Answer:

x = 2

Step-by-step explanation:

using the method of cross- multiplication

[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] ⇒ ad = bc

given [tex]\frac{x+4}{3}[/tex] = [tex]\frac{x+6}{4}[/tex], then

4(x + 4) = 3(x + 6) ← distribute parenthesis

4x + 16 = 3x + 18 ( subtract 3x from both sides )

x + 16 = 18 ( subtract 16 from both sides )

x = 2
