13=-4x-9 what is x plz help

x = -

Step-by-step explanation:

Given

13 = - 4x - 9 ( add 9 to both sides )

22 = - 4 ( divide both sides by - 4 )

= x, thus

x = -

x = -5.5

Step-by-step explanation:

The given equation is

13 = -4x-9

bringing the constants on left hand side and leaving the variables on the right hand side

13+9 = -4x

22 = -4x

so x=22/-4

simplifying it we get

x= -11/2

or x = -5.5

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
