Question

7x + 1 < 3(x + 5), where x n

Answer 1

$\huge {\fcolorbox{black}{white} { \color{magenta}A}} {\fcolorbox {black}{white}{ \color{blue}{n}}}{ \fcolorbox{black}{white}{ \color{yellow}{s}}} {\fcolorbox{black}{white}{ \color{lime}{w}}} {\fcolorbox{black}{white}{ \color{aqua}{e}}}{ \fcolorbox{black}{white}{ \color{purple}{r}}}$

$\sf7x + 1 < 3(x + 5)$

$\sf \rightarrow7x + 1 < 3x + 15$

$\sf \rightarrow7x - 3x < 15 - 1$

$\sf \rightarrow4x < 14$

$\implies \sf x = \cancel\frac{14}{4} = 3.5$
