Question

Solve the following equation 1+x/-3+x = 5

Answer 1

Solution :-

Given

$\sf{ \dfrac{1 +x}{x - 3} = 5}$

By cross multiplication

$\implies \sf{ (1 + x) = 5.(x - 3)}$

$\implies \sf{ 1 + x = 5x - 15}$

$\implies \sf { 4x = 16 }$

$\implies \sf{ x = 4}$

Answer 2

SoluTion:-

$\longmapsto \sf \: \dfrac{1 + x}{ - 3 +x} = 5$

★ By doing Cross Multiplication :-

$\\ \longmapsto \sf \:(1 + x) = 5( - 3 + x) \\ \\ \longmapsto \sf \:1 + x = - 15 + 5x \\ \\ \longmapsto \sf \:1 + 15 = 5x - x \\ \\ \longmapsto \sf \:16 = 4x \\ \\ \longmapsto { \underline{ \boxed{ \purple{\sf{ \:x = 4}}}}}$
