Answer:
1 solution.
Step-by-step explanation:
-3d + 6 = 10
⇒ -3d = 10-6
⇒ -3d = 4
⇒ d =
so, d =
Answer:
x≤9
Step-by-step explanation:
x−6≤3
Add 6 to both sides of the inequality.
x≤3+6
Add 3 and 6.
x≤9

Answer:
The error is between the given and step 1
Step-by-step explanation:
the negative wasnt distributed to the 4x-3.
it would have been 8x-4x+3=5
They aren't necessarily equal because, for example, 3/2 = 1 remainder 1 and 5/4 = 1 remainder 1 aren't equal because it takes 2 x 1 = 2 + 1 = 3 while 4 x 1 = 4 + 1 = 5. They are the same quotient and remainer, except they aren't used to check if it multiplys back to the same divended.
Answer:
p = -7/3 and q = -6
Step-by-step explanation:
3p-2q=5
Substitute q-1 for 3p
q-1-2q=5
-q-1=5
q=-5-1=-6
Substitute the value of q = -6 in q-1=3p
-6-1=3p
3p=-7
p = -7/3
