Solve the equation and enter the value of x below 2(x+6)=-10

malfutka [58]

Answer:

$\huge \boxed{x=-11}$

Step-by-step explanation:

First, divide by 2 from both sides of equation.

$\displaystyle \frac{2(x+6)}{2}=\frac{-10}{2}$

Then, solve.

$\displaystyle x+6=-5$

Subtract by 6 from both sides of equation.

$\displaystyle x+6-6=-5-6$

Solve to find the answer.

$\displaystyle x=-11$ , which is our answer.

Find the domain of ( (a+b/b) − (a/a+b))÷( (a+b/a) − (b/a+b) )

Alexandra [31]

Answer:

Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, a=-b

Step-by-step explanation:

The domain refers to values for which the expression is defined.

This implies that, the denominators are not equal to zero.

$(\frac{a + b}{b} - \frac{a}{a + b}) \div ( \frac{a + b}{a} - \frac{b}{a + b})$

$(\frac{(a + b)(a + b)-ab}{b(a + b)})\div(\frac{(a + b)(a + b)-ab}{a(a + b)})$

$\frac{(a + b)(a + b)-ab}{b(a + b)} \times\frac{a(a + b)}{(a + b)(a + b)-ab}$

$\implies \frac{a}{b}$

Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, and a=-b
