2) 5x/3 = 15

Answer 1

$(1) 3x - 6 = 9 \\ \\ 3x = 9 + 6 \\ \\ 3x = 15 \: \: \: \: \: \:\\ \\ x = \frac{15}{3} \: \: \: \: \: \\ \\ x = 5 \: \: \: \: \: \: \: \\ \\</p><p>(2) 5x / 3 = 15 \\ \\ 5x = 15 × 3 \\ \\ 5x = 45 \\ \\ x = 45 / 5 </p><p>\\ \\ x = 9$

I hope this will be help you

Answer 2

Answer:

3x - 6 = 9

3x - 6 + 6 = 9 + 6

3x = 9 +6

3x = 15

3x/3 = 15/3

x = 15/3

x = 5

5x/3 = 15

3.5x/3 = 3.15

5x = 3.15

5x = 45

5x/5 = 45/5

x = 45/5

x = 9
