1. 5x= -80. x= -16
2. x - 73 = 129. x = 202
3. x/-8 = 22. x = -176
4. 2x + 8 = 8. 2x = 0. x = 0
5. 3x - 7 = 40. 3x = 47. x = 47/3
Are these two separate questions?
Answer:
t = 4
Step-by-step explanation:
13 + t = 17
t = 4
13 + 4 = 17
An easier way to solve a question like this is to subtract the number given by the answer.
Example:
17 - 13 = 4

small a
larger 2a-1
a+2a-1=41
3a=42
a=14
2a-1=2.14-1=27
