Question

What is the solution to the equation?

8x + 4 = –20



A.


x = –3


B.


x = –2


C.


x = 2


D.


x = 3

Answer 1

anyone understand this?

Answer 2

x = -3

Answer 3

how can you tell

Answer 4

A =-3
8x+4=-20
8x=-20-4
8x=-24
x=-24\8
x=-3

Answer 5

Step 1 :
Pulling out like terms :

1.1 Pull out like factors:

8x + 24 = 8•(x + 3)

Equation at the end of step 1 :

8 • (x + 3) = 0

Step 2 :

Solve 8•(x+3) = 0

Equations which are never true :

2.1 Solve 8 = 0

This equation has no solution(s). A a non-zero constant never equals zero.
Solving a Single Variable Equation :

2.2 Solve : x+3 = 0

Subtract 3 from both sides of the equation:
x = -3

Answer 6

X= -3
if you plug in -3 where the x is you can solve the equation.
8(-3)= -24
-24+4= -20
