Question

FIND THE VALUE.
please answer fast​

Answer 1

$\large\sf\underline{Given\::}$

• $\sf\:\frac{4x}{7}=4$

‎

$\large\sf\underline{To\:find\::}$

• Value of x

‎

$\large\sf\underline{Solution\::}$

$\sf\:\frac{4x}{7}=4$

• Cross multiplying

$\sf\rightarrow\:4x=4 \times 7$

$\sf\rightarrow\:4x=28$

• Transposing 4 to RHS it goes to the denominator

$\sf\rightarrow\:x=\frac{28}{4}$

• Reducing the fraction to lower terms

$\sf\rightarrow\:x=\cancel{\frac{28}{4}}$

$\small{\underline{\boxed{\mathrm\red{\rightarrow\:x\:=\:7}}}}$ ★

$\large\sf\underline{Verifying\::}$

Not sure about the answer !? Let's verify it.

For verifying we would plug the value of x as 7 in the given equation. Doing so if we get LHS = RHS our answer would be correct.

$\sf\:\frac{4x}{7}=4$

• Plugging the value of x as 7

$\sf\to\:\frac{4(7)}{7}=4$

$\sf\to\:\frac{4 \times 7}{7}=4$

$\sf\to\:\cancel{\frac{28}{7}}=4$

$\sf\to\:4 =4$

$\bf\to\:LHS\:=\:RHS$

$\large{\mathfrak\blue{hence\:verified\:!!}}$

Answer 2

$\huge{\underline{\underline{Answer~ ★᭄ꦿ᭄}}}$

$\\ \frac{4x}{7} = 4 \\ \\ = > 4x = 28 \\ \\ = > x = \frac{28}{4} \\ \\ = > x = 7$

$\large{\bf{\boxed{~~~~x = 7}}}$
