The campers asked their counselor to tell them her age. She replied, “If you add four years to my present age, the result will be two times my camper’s. Five years ago my age was 3/4 of what hers will be in eight years.” How old is the counselor?

20

Step-by-step explanation:

Camper=12

Counseler=20

20+4=24

24/2=12

20-5=15

15=3/4 of 20

12+8=20

the answer is d. 75%

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.
