Answer:

x=1 or 0

Step-by-step explanation:

because if X is 1 then 3*1 is 3 and 3+2 is five then it's bigger than -10 and smaller than 8

0*3 is 0 then 0 plus 2 is 2 which also works

(b). Solve for x and verify the result: 5x + 3 = 4/3 (1+x)

Kazeer [188]

<h2><u>Solution :</u></h2>

${\dashrightarrow\sf{5x + 3 = \dfrac{4}{3} \bigg(1 + x \bigg)}}$

${\dashrightarrow\sf{3 \bigg(5x + 3 \bigg)= 4\bigg(1 + x \bigg)}}$

${\dashrightarrow\sf{\bigg(5x \times 3 + 3 \times 3 \bigg)= \bigg(1 \times 4 + x \times 4 \bigg)}}$

${\dashrightarrow\sf{\bigg(15x + 9 \bigg)= \bigg(4 + 4x\bigg)}}$

${\dashrightarrow\sf{15x - 4x =4 - 9 }}$

${\dashrightarrow\sf{11x =4 - 9 }}$

${\dashrightarrow\sf{11x = - 5 }}$

${\dashrightarrow\sf{x = - \dfrac{5}{11}}}$

$\bigstar{\underline{\boxed{\sf{\red{x = - \dfrac{5}{11}}}}}}$

<u>∴ The value of x is -5/11.</u>

$\begin{gathered}\end{gathered}$

<h3><u>Verification :</u></h3>

${\dashrightarrow\sf{5x + 3 = \dfrac{4}{3} \bigg(1 + x \bigg)}}$

${\dashrightarrow\sf{ \bigg(\left\{5 \times - \dfrac{5}{11} \right\} + 3 \bigg)= \dfrac{4}{3} \bigg(1 + \left\{ - \dfrac{5}{10}\right\}\bigg)}}$

${\dashrightarrow\sf{ \bigg(\left\{- \dfrac{25}{11} \right\} + 3 \bigg)= \dfrac{4}{3} \bigg(1 + \left\{ - \dfrac{5}{11}\right\}\bigg)}}$

${\dashrightarrow\sf{ \bigg( \dfrac{ - ( 25 )+ (3 \times 11)}{11} \bigg)= \dfrac{4}{3} \bigg( \dfrac{(1 \times 11) - (5 \times 1)}{11}\bigg)}}$

${\dashrightarrow\sf{ \bigg( \dfrac{ - 25+ 33}{11} \bigg)= \dfrac{4}{3} \bigg( \dfrac{11 - 5}{11}\bigg)}}$

${\dashrightarrow\sf{ \bigg( \dfrac{8}{11} \bigg)= \dfrac{4}{3} \bigg( \dfrac{6}{11}\bigg)}}$

${\dashrightarrow\sf{ \bigg( \dfrac{8}{11} \bigg)= \bigg(\dfrac{4}{3} \times \dfrac{6}{11}\bigg)}}$

${\dashrightarrow\sf{ \bigg( \dfrac{8}{11} \bigg)= \bigg(\dfrac{4 \times 6}{3 \times 11}\bigg)}}$

${\dashrightarrow\sf{ \bigg( \dfrac{8}{11} \bigg)= \bigg(\dfrac{24}{33}\bigg)}}$

${\dashrightarrow\sf{ \bigg( \dfrac{8}{11} \bigg)= \bigg(\cancel{\dfrac{24}{33}}\bigg)}}$

${\dashrightarrow\sf{ \bigg( \dfrac{8}{11} \bigg)= \bigg({\dfrac{8}{11}}\bigg)}}$

$\bigstar{\underline{\boxed{\sf{\red{LHS = RHS}}}}}$

<u>∴ Hence Verified !</u>
