4.5+1.5k=18-3k

Answer 1

Answer:

4.5+1.5k=18-3k

1.5k+3k=18-4.5

4.5k=13.5

k=3

Answer 2

Step-by-step explanation:

$\huge \underline{Answer - }$

$4.5 + 1.5 k = 18 - 3k \\ \\ 1.5k + 3k = 18 - 4.5 \\ \\ 4.5k = 13.5 \\ \\ k = \frac{13.5}{4.5} \\ \\ \fbox\bold{k = 3} \\ \\ \bold{Checking - } \\ \\ Substituting \: the \: value \: of \: k \: on \: \\ \bold{4.5 + 1.5 k = 18 - 3k} \\ \\ 4.5 + 1.5 \bold{(3) }= 18 - 3 \bold{(3)} \\ \\ 4.5 + 4.5 = 18 - 9 \\ \\ 9 = 9 \\ \\ LHS = RHS \\ \\ Hence, \\ The \: value \: of \: \bold{k = 3} \: is \: absolutely \: correct$
