Answer:

<h2>(-1) + (+8) = 7</h2>

Step-by-step explanation:

(+)(+) = (+)

(-)(+) = (+)(-) = (-)

(-)(-) = (+)

--------------------------------------------

(-1) + (+8)= (-1) + 8      <em>use the commutative property a + b = b + a</em>

= 8 + (-1) = 8 - 1 = 7

Solve 7x - 12 = k for x
shtirl [24]

Answer:

x = 1/7(k+12)

Step-by-step explanation:

7x - 12 = k

Add 12 to each side

7x - 12+12 = k+12

7x = k+12

Divide each side by 7

7x/7 = (k+12)/7

x = 1/7(k+12)
