What is x? −4(3x+1)+x−3=15

Step-by-step explanation:

So

-4 * 3x = -12x

-4*1 = -4

Equation: -12x + -4 + x -3 = 15

move -12x and x to the other side, and 15 to the other/

Equation: -4+ (-3)-15 = 12x - x

simplified: -22=11x

x= -22 divided by 11

x= -2

x = -2

Step-by-step explanation:

-4(3x +1) = -12x - 4

-12x - 4 + x - 3 = 15

       +4              +4

-12x + x - 3 = 19

-11x - 3 = 19

      +3    +3

-11x = 22

22 / -11 = -2

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

c: lkllmn.
