Thirteen plus 5 times a number is no more than 30.
step1:
step2:
step3:
step4:

x < 3.4

Step-by-step explanation:

13 + 5times a number(x) is nor more than(less than or equal to/<) 30

13 + 5x  < 30

-13           -13

    5x < 17

    5     5

 x <  3.4

on the number line, it will be a shaded in circle on 3.4, and the arrow will be pointing to the left.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
