2/18 + 5/18 = 7/18
2+14=16
-18
5 - 12 = -7
1.22222, or 22 over 18 (22/18), or 1 and 4 over 18 (1 4/18)
-5+7--4+12 = 18
The problem of -5 plus 7 - (-4 plus -12) is equal to 18.
72 is.
It is 5*7*4 = 140
5 plus the product of 7 and n.
5 + (2 x 7) - (18/5) = 15.4
5/6 plus 7/9 is 1 and 11/18.
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
7*2+5=19 Check the order of operation.
2/18 + 5/18 = 7/18
-3x+7=2x-18 ---> 7+18=2x-3x ----> 25=5x ----> x=5
7/9 + 5/6 = 14/18 + 15/18 = 29/18 or 111/18
