Question

6x+7=3x+16 ?

Answer 1

Answer:

x = 3

x = -1

x = -9

x = 25

x = 8

x = -29

x = -1

x = 4/6

Step-by-step explanation:

For each of these, you simply subtract the similars from each other. Basically meaning, the number with variables will be subtracted from each other while the constants will be substrates from each other. In the first case, you’ll subtract 3x from 6x and be left with 3x. Then it’d be 3x + 7 = 16. Now you don’t want to subtract 16 from 7 as to not leave the right side empty but rather to have one coefficient with it’s variable on one side and a constant on the other, you’ll subtract 7 from 16 and get 9. 3x = 9. Then to get the x by itself, you’d divide because (3x) is multiplication, basically (3*x) so to rid one value from a multiplication problem, you’d have to divide. So you’d divide 3 from both sides. And get x = 3.
