Answer 2

✧$\huge \mathcal \red {\underline{\underline{A}}}$ $\huge \mathcal \green {\underline{\underline{N}}}$ $\huge \mathcal \pink {\underline{\underline{S}}}$ $\huge \mathcal \blue {\underline{\underline{W}}}$ $\huge \mathcal \orange {\underline{\underline {E}}}$ $\huge \mathcal \purple {\underline{\underline{R}}}$✧

Given :

✵ $\frac {x} {12} + 5 = 10$

✵ $4y + 5 = 45$

✵ $\frac {4x}{7} - 10 = 14$

To find :

The value of x

Solution :

✵ $\frac {x} {12} + 5 = 10$

➜ $\frac {x} {12} = 10 - 5$

➜ $\frac {x} {12} = 5$

➜ $x = 5 × 12$

➜ $x = 60$

✵ $4y + 5 = 45$

➜ $4y = 45 - 5$

➜ $4y = 40$

➜ $y = \frac {40}{4}$

➜ $y = 10$

✵ $\frac {4x}{7} - 10 = 14$

➜ $\frac {4x}{7} = 14 + 10$

➜ $\frac {4x}{7} = 24$

➜ $x = \frac {24 × 7}{4}$

➜ $x = 42$

Results :

✵ $\frac {x} {12} + 5 = 10$

$\implies$ Here, the value of x = 60

✵ $4y + 5 = 45$

$\implies$ Here, the value of x = 10

✵ $\frac {4x}{7} - 10 = 14$

$\implies$ Here, the value of x = 42
