6) 3x - 5 = 10

7) 36 = 4x + 12

8) 3(x + 2) = 36

9) 7(2x - 15) = 63

Answer 1

6) x=5

7)x=6

8)x=10

9)x=12

Explanation:

6) 3x-5=10. 7) 36=4x+12. 8) 3(x+2)=36

+5 +5. - 12. - 12. 3x + 6=36

3x = 15. 24 = 4x. - 6. -6

÷3. ÷3. ÷4. ÷4. 3x=30

x=5. 6 = x. x = 10

9) 7(2x-15)=63

14x - 105=63

+105. +105

14x = 168

÷14. ÷14

x=12
