Solve the equation. check you solution. show work 21(2-x) +12x=44

x = -2/9

Step-by-step explanation:

21(2 - x) + 12x = 44

42 - 21x + 12x = 44

- 21x + 12x = 44 - 42

- 9x = 2

- x = 2/9

x = -2/9

4 & 3

step-by-step explanation:

factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
