Question

Determine o valor de x.

Answer 1

Explicação passo-a-passo:

Pelo Teorema de Tales:

$\sf \dfrac{4x+1}{16}=\dfrac{x+2}{18}$

$\sf 18\cdot(4x+1)=16\cdot(x+2)$

$\sf 72x+18=16x+32$

$\sf 72x-16x=32-18$

$\sf 56x=14$

$\sf x=\dfrac{14}{56}$

$\sf \red{x=\dfrac{1}{4}}$

Answer 2

Oie, Td Bom?!

[4x + 1]/16 = [x + 2]/18

18(4x + 1) = 16(x + 2)

72x + 18 = 16x + 32

72x - 16x = 32 - 18

56x = 14

x = 14/56

x = [14 ÷ 14]/[56 ÷ 14]

x = 1/4
