➤ How to solve ?
⠀⠀⠀⠀
That's quite easy but you need to recall the BODMAS rule .
⠀⠀⠀⠀
BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction
⠀⠀⠀⠀
In this equation we will solve the bracket then we will apply further BODMAS rule

SolutiOn :
➠ 7x + 31 = 8x - 1 ( 27x + 3 ) -3
➠ 7x + 31 = 8x - 27x - 3 - 3
Now, we will bring the variable on left hand side and constants on right hand side
➠ 7x - 8x + 27x = - 31 - 3 - 3
➠ 26x = -37
➠ x = -37/ 26
➠ x = - 1.42
∴ The value of x is -1.42 .

Its really easy. just look at the middle line. now the sides are only the answers including the square roots. so the line in the middle represents 12. The answer is 12
The second integer is greater than the first integer
Increase in cash = 325,000- 250,000 = 75,000
increase percentage = 75,000 / 250,000 × 100 = 30 % Increase
The answer is 16, all you must do is substitute x with the given value then solve, so 23-7
