Question

what is the answer for -7x+7(-2x+25)=-56

Answer 1

Hey mate ☺️

_______________________

$- 7x + 7( - 2x + 25) = - 56 \\ \\ - 7x - 14x + 175 = - 56 \\ \\ - 21x + 175 = - 56 \\ \\ - 21x = - 56 - 175 \\ \\ \cancel - 21x = \cancel - 231 \\ \\ x = \frac{231}{21} \\ \\ x = 11$

Answer 2

Hi there!

_______________________

Given :

- 7x + 7( - 2x + 25) = - 56

To find :

Value of x.

$\bold{\underline{Solution :}}$

$- 7x + 7( - 2x + 25) = - 56 \\ \\ - 7x - 14x + 175 = - 56 \\ \\ - 21x + 175 = - 56 \\ \\ - 21x = - 56 - 175 \\ \\ \cancel - 21x = \cancel - 231 \\ \\ x = \frac{231}{21} \\ \\ x = 11$

$\bold{\underline{Verification :}}$

Putting the value of x in - 7x + 7(- 2x + 25) = -56

$- 7(11) + 7( - 2 \times 11 + 25) = - 56 \\ \\ - 77 + 7( - 22 + 25) = - 56 \\ \\ - 77 - 154 + 175 = - 56 \\ \\ - 231 + 175 = - 56 \\ \\ - 56 = - 56 \\ \\ \bold{ \therefore lhs = rhs}$

Hence the value of x is 11.
