Question

Solve this 15/4 - 7x = 9​

Answer 1

Given:

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

Now solve it as

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

$\frac{15-9\times4}{4}=7x$

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

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

$\frac{-21}{4\times7} =x$

$x=\frac{-21}{28}$

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

Hence the answer is -3/4

Answer 2

As per data given in the question,

We have to determine the value of "x" in the given expression - $\frac{15}{4}-7 x=9$

For finding the value of x we will solve the given expression by using BODMAS rule,  

Now solve it as

$\begin{array}{l}\frac{15}{4}-9=7 x \\\frac{15-9 \times 4}{4}=7 x \\\frac{15-36}{4}=7 x \\\frac{-21}{4}=7 x \\\frac{-21}{4 \times 7}=x \\x=\frac{-21}{28} \\x=-\frac{3}{4}\end{array}$

Hence the value of "x" will be $-3 / 4$.
