Answer:
1. r = 12
Solution:
[tex]r + 6 - 8 = 10[/tex]
[tex]r - 2 = 10[/tex]
[tex]r = 10 + 2[/tex]
[tex]r = 12[/tex]
2. e = 9
Solution:
[tex]3e = 27[/tex]
[tex] \frac{3e}{3} = \frac{27}{3} [/tex]
[tex]e = 9[/tex]
3. x = 4
Solution:
[tex]2x + 2 = 10[/tex]
[tex]2x = 10 - 2[/tex]
[tex]2x = 8[/tex]
[tex] \frac{2x}{2} = \frac{8}{2} [/tex]
[tex]x = 4[/tex]
