You have a deck of t trading cards. You give 20 cards to a friend and have 2 left for yourself. How many cards were in the original deck? Write a simpler, equivalent equation to solve and find the number of cards in the deck.

t = 22

Step-by-step explanation:

t = trading cards

t - 20 = 2

t - 20 = 2

 +20   +20

t = 22

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

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

1

4

)=(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.

−3x

−3
