Question

if 7x - 9 equals 15, what is the value of 7x +1

Answer 1

Answer:

25

Step-by-step explanation:

First,

7x - 9 = 15

=> 7x = 15 + 9

=> 7x = 24

$= > x = \frac{24}{7}$

Now putting its value in 7x + 1,

= 7x + 1

$= 7 (\frac{24}{7} ) + 1$

$= 7 \times \frac{24}{7} + 1$

= 24 + 1

= 25 (Ans)
