Yes.
This doesn't make any math sense:2⁴ - 1 + 21 = 14 = 7 +3 x 5
To find this: You know (B+C) = 7. Therefore you know (A+A )= 21 - (B+C). Therefore 21-7 = 14. So now you know (A+A) = 14. So you divide (A+A)/2. This equals 7. Therefore A = 7.
5y+14+y = 3y-7 5y+y-3y = -7-14 3y = -21 y = -7
-14 + 3p = -9p - 21 add 14 and 9p to both sides, then 12p = -7 p = -7/12

5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
x/11 + 21 = 7 x/11 = -14 x = -154
x/11 + 21 = 7 x/11 = -14 x = -154
m=-21/2 or m=-10.5
?+14=7+7 ?=0 7+7=14

2/3 + 1/7 + 4/6 = 14/21 + 3/21 + 14/21 = 31/21 = 1 10/21
