Step-by-step explanation:
x+2+x=180
2x=180-2
2x=178
x=89
Answer: r=14
Step-by-step explanation:
because they are vertical angles
7r+6=8r-8
solving for r you get
r=14
Answer: X= -9
Step-by-step explanation:
Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.
Then subtract or add the like terms
5x-3x and 20+3. It will be 2x+23=5
Then add -23 to both sides
It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x
2x/2=-18/2 then the final answer is x= -9. I hope it help
