$\sf{ }$

$\large\bf{{\underline{To~solve}}:}$

$\tt{~~~~~~~~~~~~~~5(3-x)+1=3(x+4)}$

$\tt{»-\longrightarrow 15-5x+1=3x+12}$

$\tt{»-\longrightarrow 16-5x=3x+12}$

$\tt{»-\longrightarrow -5x-3x=12-16}$

$\tt{»-\longrightarrow -8x=-4}$

$\tt{»-\longrightarrow 8x=4}$

$\tt{»-\longrightarrow x={\dfrac{4}{8}}}$

$\tt{»-\longrightarrow x={\color{blue}{\underline{\boxed{\bf ~{\dfrac{1}{2}}~}}}}}$

Answer 2

$\huge\star\:\underline{\mathtt{\red{A}{\pink{N}{\blue{S}{\green{W}{\purple{E}{\orange{R}}}}}}}}\:{\star}$

$5(3 - x) + 1 = 3(x + 4) \\ 15 - 5x + 1 = 3x + 12 \\ 16 - 5x = 3x + 12 \\ 16 - 12 = 3x + 5x \\ 4 = 8x \\ \frac{4}{8} = x \\ \pink{ \frac{1}{2} = x (Ans)}$
