Answer 1

$\sf\purple{Question:-}$

• If Renu spends 4/5 of her income and her monthly income is $15,000 then find the savings.

$\sf\orange{Solution:-}$

$money \: spent = \frac{4}{5} \times 15000$

$= 12000$

$money \: saved \: = 15000 - 12000$

$= 3000$

➯ hence , Renu saved $3000

$\sf\purple{Question:-}$

• $\frac{6x + 1}{2} + 1 = \frac{7x - 3}{3}$

$\sf\orange{Solution:-}$ l

$\frac{6x + 1 + 2}{2} = \frac{7x - 3}{3}$

$\frac{6x + 3}{2} = \frac{7x - 3}{3}$

$3(6x + 3) = 2(7x - 3)$

$18x + 9 = 14x - 6$

$18x - 14x = - 6 - 9$

$4x = - 15$

$x = \frac{ - 15}{ \: \: \: 4}$

❏ by LHS

$\frac{6x + 1 + 1}{2}$

$\frac{6x - 15 \: by \: 4 + 1}{2} + 1$

$\frac{ - 45 \: by \: 2 + 1}{2}$

$\frac{ - 45 \: by \: 2 + 2}{2} + 1 = ( - \frac{43}{2} \div 2) + 1$

$( - \frac{43}{2} \times \frac{1}{2} + 1 = \frac{ - 43}{ \: \: \: 4} + 1$

$\frac{ - 43 + 4}{ \: \: 4} = - \frac{39}{4}$

Final Answer:-

$\frac{ - 39}{ \: \: 4}$

Answer 2

Answer:

1.MONTHLY INCOME OF RENU=$15000

SHE SPENT 4/5 OF IT:

$\frac{4}{5} \times 15000 = 3000$

SHE SPENT $3000

ACCORDING TO THE FORMULA:

INCOME =EXPENDITURE +SAVING.

=$15000=$3000+SAVING

=>SAVING=$15000-3000=$12000. ( ANSAWER)

2.

$6x + \frac{1}{2} + 1 = 7x - \frac{3}{3} \\ \\ = > 6x + \frac{3}{2} = 7x - 1 \\ \\ = > \frac{3}{2} + 1 = 7x - 6x \\ \\ = > \frac{5}{2} = x$
