Question

Check whether the value3a+2=20 of at a=6 make equation true​

Answer 1

Given :

• Equation = 3a + 2 = 20
• a = 6

To Find :

• Check whether equation is true or not

$\\ \qquad{\rule{200pt}{2pt}}$

SolutioN :

$\maltese$ Checking the Equation :

$\begin{gathered} \qquad \; \longrightarrow \; \; \sf { 3a + 2 = 20 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; \sf { 3(6) + 2 = 20 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; \sf { \bigg( 3 \times 6 \bigg) + 2 = 20 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; \sf { 18 + 2 = 20 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; \sf { 20 = 20 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longrightarrow \; \; {\underline{\boxed{\pmb{\sf{ LHS = RHS }}}}} \; {\purple{\pmb{\bigstar}}} \\ \\ \\ \end{gathered}$

$\therefore \;$ The Given equation is True .
