Answer 2

Given :

${\underline{\sf \green{ Equation: 3y=ax+7}} }$

$\red\dashrightarrow\underline{\underline{\sf \green{ x = \frac{1}{2} }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{ y = \frac{1}{3} }} }$

To do:-

Substitute

$\frac{1}{2}$

in place of x

$\frac{1}{3}$

in place of y

$\red\dashrightarrow\underline{\underline{\sf \green{ 3 \times ( \frac{1}{3}) = a \times \frac{1}{2} + 7 }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{ \frac{3}{3} =a \times \: \frac{15}{2} }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{ 1 = a \times\frac{15}{2} }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{ \: a = \frac{2}{15} }} }$
