The sum of a number times 7 and 24 is at most -18. Use the variable x for the unknown number.

unknown number=-6

Step-by-step explanation:

Let x be the unknown number.

7x+24=-18

      7x=-18-24

          =-42

        x=-42÷7

          =-6

Hence, unknown number=-6.

Step-by-step explanation:

10n + 27 >= -18

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
