Question

x/4+5=9/7. answer the question​

Answer 1

The answer is -14.8

Answer 2

Answer

${\sf \dashrightarrow \dfrac{x}{4} + 5 = \dfrac{9}{7}}$

${\sf \dashrightarrow \dfrac{x}{4} + \dfrac{5}{1} = \dfrac{9}{7}}$

${\sf \dashrightarrow \dfrac{x + 20}{4} = \dfrac{9}{7}}$

${\sf \dashrightarrow 7 (x + 20) = 9 (4)}$

${\sf \dashrightarrow 7x + 140 = 36}$

${\sf \dashrightarrow 7x = 36 - 140}$

${\sf \dashrightarrow 7x = (-104)}$

${\sf \dashrightarrow x = \dfrac{-104}{7}}$

Hence, the value of x is $\sf \dfrac{-104}{7}$

Verification

${\sf \dashrightarrow \dfrac{x}{4} + 5 = \dfrac{9}{7}}$

$\sf \dashrightarrow \dfrac{\dfrac{-104}{7}}{4} + 5 = \dfrac{9}{7}$

${\sf \dashrightarrow \dfrac{-104}{7} \times \dfrac{1}{4} + 5 = \dfrac{9}{7}}$

${\sf \dashrightarrow \dfrac{-26}{7} + \dfrac{5}{1} = \dfrac{9}{7}}$

${\sf \dashrightarrow \dfrac{-26 + 35}{7} = \dfrac{9}{7}}$

${\sf \dashrightarrow \dfrac{9}{7} = \dfrac{9}{7}}$

${\sf \dashrightarrow LHS = RHS}$
