3t+11 = 29 3t = 29-11 3t = 18 t = 6
Identity property of addition.
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
The answer is 209. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
16 + 16 + 16 + 17 + 18 + 18 + 18 + 19 + 19 + 20 + 20 + 20 + 21 = 238
29 + - 3 + 6 + - 41 + 18 = 29 - 3 + 6 + 41+ 18 =93
The answer is 29. 18 + 11 _______ 29
18.+ 11 = 29

17/18 + 12/18 = 29/18
3t+11 = 29 3t = 29-11 3t = 18 t = 6
2 and 4/18 + 4 and 3/18 = 6 and 7/18
7/9 + 5/6 = 14/18 + 15/18 = 29/18 or 111/18
5/6 plus 7/9 is 1 and 11/18.
