Answer 1

❶ 1st QUESTION ❶

♣GIVEN :-

• a = 5

♣TO FIND :-

• The value of $\frak{ \dfrac{4a}{10}}$

♣SOLUTION :-

❐ Putting the value ❐

$➱ \: \frak{ \dfrac{4a}{10} }$

$➱ \: \frak{ \dfrac{4 \times 5}{10} }$

$➱ \: \frak{ \dfrac{20}{10} }$

$➱ \: \frak{ \dfrac{ \cancel{20} ^ { \large2}}{ \cancel{10} _ {\large{1}} } }$

$➠ \: \huge\frak \red{ 2 }$

HENCE SOLVED :)

❷ 2nd QUESTION ❷

♣GIVEN :-

• $\frak{2x + 7 = 3\bigg(x-1\bigg)}$

♣TO FIND :-

• The value of x

♣SOLUTION :-

❐ Putting all values ❐

$➱ \: \frak{2x + 7 = 3\bigg(x-1\bigg)}$

$➱ \: \frak{2x + 7 = 3x - 3}$

$➱ \: \frak{2x - 3x = - 3 - 7}$

$➱ \: \frak{ \cancel - x = \cancel - 10}$

$➠ \: \huge\frak \red{ x = 10 }$

HENCE SOLVED :)

Answer 2

(A)

4a/10

A = 5

Put the value of a,

4x5/10

20/10

=2 proved

(B)

2x + 7 = 3 (x-1)

2x+7=3x-3

2x-3x=-3-7

-x=-10

x=10 Proved
