Answer:
x = -9
Step-by-step explanation:
12 + 2x + 24 = 27 + x
(12 + 24) + 2x = 27 + x
36 + 2x = 27 + x
subtract 27 from both sides
36-27 + 2x = 27-27 + x
9 + 2x = x
subtract x from both sides
9 + x = 0
subtract 9 from both sides
x = -9
(the steps could've been faster but that shows the most work)
check:
12 + 2(-9) + 24 = 27 + (-9)
36 - 18 = 18
18 = 18
True!
so -9 is correct

Since there are 6 equal parts and Theo planted in only 5 of them, he planted seeds in 5/6 of the garden (OR 5/6 = 10/12 = 15/18 = 20/24 = 25/30 = 30/36 = 35/42 = 40/48 = 45/54 = 50/60 = 55/66 = 60/72 = 65/78 = 70/84 = 75/90 = 80/96 = 85/102 = 90/108 = 95/114 = 100/120 - from <span>https://goo.gl/RTbV4R</span>)
