Solve for x.

−2x+3=15
Enter your answer in the box.

x =

 x = -6

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -2x - 12  =   -2 • (x + 6)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x+6 = 0

Subtract  6  from both sides of the equation :

                     x = -6

One solution was found :

                  x = -6

X = -6

Step-by-step explanation:

-2X + 3 = 15

Collect like terms

-2X = 15 - 3

-2X = 12

Divide through with -2

X = -6

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
