Answer:

{x}^{2}  - 14x - 49 = 0

{x}^{2}  - (7  + 7)x - 49 = 0

{x}^{2}  - 7x - 7x - 49 = 0

x(x - 7) + 7(x - 7) = 0

(x - 7)(x + 7) = 0

NOW,

x-7=0

or,x=7

And,

x+7=0

or,x= -7

THEREFORE, x= 7, -7

hope it helps you,

Which of the following equations is equivalent to 4[x + 2(3x - 7)] = 22x - 65
Nataly_w [17]

Answer:

See the equation simplified below.

Step-by-step explanation:

The equation simplifies to the following equations:

4[x + 2(3x - 7)] = 22x - 65

4[x+6x-14] = 22x - 65

4x+24x - 56 = 22x - 65

28x - 56 = 22x - 65

6x - 56 = -65

6x = -9

x = -3/2
