Answer: 12.6
Step-by-step explanation: because it’s the right answer
Answer/Step-by-step explanation:
1. x = -3.6
Add 1 on both sides.
18x = 23x + 18
Subtract 23x on both sides.
Combine like terms.
Divide the answer.
-5x = 18
x = -3.6
2. x = 11/3 (2.66666...)
Add 5 on both sides.
6x = 3x + 11
Subtract 3x on both sides.
Combine like terms.
Divide the answer.
3x = 11
x = 11/3
3. x = 23
Subtract 12 on both sides.
5x = 6x - 23
Subtract 6x on both sides.
Combine like terms.
Divide the answer.
-x = -23
x=23
(that's all.)
Answer:
x=4
Step-by-step explanation:
21/10 more than y is 19/5 CORRECT
17/10 + 21/10 = 38/10 simplified to 19/5
34/5 less than y is -51/10 CORRECT
17/10 - 34/5 = 17/10 - 34/5*2/2 = 17/10 - 68/10 = (17-68)/10 = -51/10
15/2 more than y is 29/5 INCORRECT
17/10 + 15/2 = 17/10 + 15/2 * 5/5 = 17/10 + 75/10 = (17+75)/10 = 92/10
18/5 less than y is -53/10 INCORRECT
17/10 - 18/5 = 17/10 - 18/5 * 2/2 = 17/10 - 36/10 = (17-36)/10 = -19/10
