9x-3>= 4(3x+3) — step-by-step solution

⚠ 9x is read as the product 9*x: for a power, write 9^x

⚠ 4( is read as the product 4*(...): for a power, write 4^(...)

⚠ 3x is read as the product 3*x: for a power, write 3^x

Let's solve in

ℝ

9 x - 3 >= 4 \cdot (3 x + 3)

9 x - 3 >= 12 x + 12

- 3 - 12 >= 12 x - 9 x

ℹ

- 3 - 12

-15

‖

12 x - 9 x

3 x

-15 >= 3 x

x =< - \frac{15}{3}

▶Solution found:

x =< -5
