Question

15/4 -7x = 9 can someone say how to do this sum pls ?

Answer 1

Answer:

$\frac{-3}{4}$

Step-by-step explanation:

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

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

LCM = 4

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

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

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

x = $\frac{-21}{4x7}$

cancelling -21 by 7 to get -3

∴ x = $\frac{-3}{4}$
