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
