Question

3(5x – 10) < 30x solve for x

Answer 1

Step-by-step explanation:

Step 1:  Distribute

$3(5x - 10) < 30x$

$(3 * 5x) + (3 * -10) < 30x$

$15x - 30 < 30x$

Step 2:  Subtract 15x from both sides

$15x - 15x - 30 < 30x - 15x$

$-30 < 15x$

Step 3:  Divide both sides by 15

$-30 / 15 < 15x / 15$

$-2 < x$

Answer:  $x > -2$
