Step-by-step explanation:
Eight friends went to a hockey game. The price admission per person was $x. This means that the total amount paid by the eight friends for admission would be
8 × x = $8x
Four of the friends paid and extra $6 each for a player guide book. This means that the total amount paid by four of the friends for the player guide book would be
4 × 6 = $24
Therefore, the expression that represents the total amount spent by the eight friends would be
8x + 24
Take the square root of both sides
remember to take the positive and negative root
2x+5=-7 or
2x+5=7
solve each
2x+5=-7
subtract 5
2x=-12
divide 2
x=-6
2x+5=7
subtract 5
2x=2
divid 2
x=1
x=-6 or 1
