Solve the inequality. 9(2 − x) − 4(2 − 3x) > 9

Remove both sets of brackets.

18 - 9x - 8 + 12x > 9 Collect like terms on the left.

12x - 9x + 18 - 8 > 9

3x + 10 > 9 Subtract 10 from both sides.

3x > 9 - 10

3x > - 1 divide by 3

x > -1/3

Notice what the graph is telling you. A blue dotted line is going through x = - 1/3 or - 0.3333

Everything to the right of - 0.333 is colored blue and that means anything to the right if going to be a solution to the inequality. To confirm this for yourself, try zero and 1. Both should give larger than 9 solutions.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
