Question

y = 3, x =?

4y+6(5-2x)=6​

Answer 1

4y + 6(5 - 2x) = 6

12 + 30 - 12x = 6

42 - 12x = 6

12x = 36

x = 3

Answer 2

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

$\tt{~~~~~~~~~~~4y+6(5-2x)=6~~~when~~~y=3}$

$\tt{:\implies 4(3)+6(5-2x)=6}$

$\tt{:\implies 12+6(5-2x)=6}$

$\tt{:\implies 12+30-12x=6}$

$\tt{:\implies 42-12x=6}$

$\tt{:\implies -12x=6-42}$

$\tt{:\implies -12x=-36}$

$\tt{:\implies 12x=36}$

$\tt{:\implies x={\dfrac{36}{12}}}$

$\tt{:\implies x={\colorbox{orange}{\color{black}{\bf 3}}}}$
