Verified answer
x greater or equal than -3
7x-6>or=6x-9
x-6>or=-9
x>or=-3
make a line graph plotting a shaded in circle on 3 and the arrow going to the right, all integers greater than or equal to 3
7x - 6 ≥ 6x - 9
-->
7x - 6 + 6 ≥ 6x - 9 + 6
-->
7x ≥ 6x - 3
-->
7x - 6x ≥ 6x -6x - 3
-->
x ≥ -3

solve it as if there wasnt >=
7x - 6 ≥ 6x - 9
7x - 6x ≥ -9 +6
x ≥ -3
subtract 6x from both sides, and add 6 to both sides. now you have .... -3 > x
7x - 6 ≥ 6x - 9
x-6≥ -9
x≥ -3
use MATH :)
use GRAPH PAPER :)
