2/3 (3x + 9) = -2(2x + 6)

Step by step

2/3 * 3x and 2/3 * 9 = 2x and 6

which is 2x + 6 (since 6 is a positive put a plus 6 [ + 6 ] )

-2 * 2x and -2 * 6 = -4x and -12

which is -4x - 12 (since 12 is negative put a minus 12 [ - 12 ])

We now have 2x + 6 = -4x - 12

now add 4x on both sides

2x + 6 + 4x = −4x − 12 + 4x

6x + 6 = −12

now Subtract 6 from both sides.

6x + 6 − 6 = −12−6

6x=−18

finally Divide both sides by 6.

6x/6 = -18/6

x = -3

The answer is x=−3
