What equation is equivalent to the equation 3x+6=4x+7

x = -1

Step-by-step explanation:

3x+6=4x+7   (subtract 6 from both sides)

3x = 4x + 7 -6

3x = 4x  +1    (subtract 4x from both sides)

3x - 4x = 1

-x = 1  (divide both sides by -1)

x = -1

i just took the test, the correct answer is .. 31.5 in.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
