Find the value of x that makes the equation true.

7x = –56

a.
–49

b.
–392

c.
–63

d.
–8

  D.  -8

Step-by-step explanation:

Since you know your times tables, you know that 7×8 = 56. Then by the rules of signs, 7×(-8) = -56. The value of x is -8.

In terms of equation solving process, you would solve this equation by multiplying both sides by 1/7. This will make the coefficient of x be 1.

  (1/7)(7x) = (1/7)(-56)

  x = -8
