Question

(7x-5)-4(2+5x)=10(2-x) ​

Answer 1

The solution is provided below :

Given that,

$(7x - 5) - 4(2 + 5x) = 10(2 - x)$

To find : The value of x

So, to solve this mathematical problem, first we have to remove the brackets. On removing the brackets some of the sign will be changed.

For example : - and + sign together results in - sign.

So,

$7x - 5 - 8 - 20x = 20 - 10x$

Now, we have to bring the numbers having same variables on the same sides.

$7x - 20x + 10x = 20 + 5 + 8$

$7x - 10x = 25 + 8$

$- 3x = 33$

$x = \frac{ - 33}{3}$

$x = - 11$

Hence, the value of x is -11

Answer 2

Given: $(7x-5)-4(2+5x)=10(2-x)$

To Find: Find the value of $x$.

Step-by-step explanation:

∴ $(7x-5)-4(2+5x)=10(2-x)$

First break the bracket,

⇒$7x-5-8-20x=20-10x$

Take all $x$ terms in one sides,

⇒$7x-20x+10x=20+8+5$

⇒$-3x=33$

Multiplying minus on both sides,

⇒$-(-3x)=-33$

⇒$3x=-33$

⇒$x=\frac{-33}{3}$

∴ $x=-11$

So, The value of $x$ is $-11$.
