֍TO FIND:

• value of x = ?

֍SOLUTION:

$\bold {ACCORDING \: TO \: QUESTION}$

40% of 70 = 30% of 80 + x

$\tt⎇ \frac{40}{100} \times 70 = \frac{30}{100} \times 80 + x$

solve it,

$\tt⎇ \frac{2800}{100} = \frac{2400}{100} + x$

$\tt⎇ \frac{28 \cancel{00}}{1 \cancel{00}} = \frac{24 \cancel{00}}{1 \cancel{00}} + x$

$\tt⎇ 28 = 24 + x$

$\tt⎇ x = 28 - 24$

$\tt⎇ x = 4$

Hence, x = 4.
