x = 3

hope it will be right

Answer 2

Given -

$2(x + 5) + 3(x - 10) = - 5$

We have to find out the value of x.

given equation,

$2(x + 5) + 3(x - 10) = - 5$

Multiply the numbers with bracket we get

$2x + 10 + 3x - 30 = - 5$

The number having same variable is get added

$5x - 20 = - 5$

Shift -20 to right side it becomes+20

$5x = - 5 + 20$

$5x = 15$

Divide both sides by 5 we. get

$x = 3$

Therefore,

The value of x is 3 .

By the value of x=3 in LHS of given equation you get the RHS . These shows our ans is right

LHS =

$2(x + 5) + 3(x - 10) \\ = 2(3 + 5) + 3(3- 10) \\ =2(8) + 3( - 7) \\ = 16 - 21 \\ = - 5$

-5 = RHS

So, answer is verified
