25pts

18 work for company A and 13 for company B

Step-by-step explanation:

Company A = A

Company B = B

A = B + 5

A + B = 31

B + 5 + B = 31

2B + 5 = 31

2B = 26

B = 13 -->

A = 13 + 5

A = 18

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(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.
