Question

Solve the equation:$\frac{15}{4}-7x=9$

Answer 1

Linear equation:

$\frac{15}{4}-7x=9$

$\Rightarrow$$7x=\frac{15}{4}-9$

$\Rightarrow$$7x=\frac{15-36}{4}$

$\Rightarrow$$7x=\frac{-21}{4}$

$\Rightarrow$$x=\frac{-21}{4\times 7}$

$\Rightarrow$$x=\frac{-3}{4}$

Hence, the value of $x=\frac{-3}{4}$.
