−4(2x+5)+2x+3= −11 what is x

x = -1

Step-by-step explanation:

-4(2x + 5) = -8x - 20

-8x - 20 + 2x + 3 = -11

      +20                 +20

-8x + 2x + 3 = 9

               -3    -3

-8x + 2x = 6

-6x = 6

x = -1

X=-1

Step-by-step explanation:

− 4 ( 2 + 5 ) + 2 + 3 = − 1 1

− 8 − 2 0 + 2 + 3 = − 1 1

− 8 − 1 7 + 2 = − 1 1

− 6 − 1 7 = − 1 1

− 6 − 1 7 + 1 7 = − 1 1 + 1 7

−6 = 6

Then, divide both sides of the equation by the same term: 6

and you get x=-1

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
