(7x-10) - (-6x-8)
distribute the negative to the (-6x-8)
(7x-10) + 6x+8
disregard the parenthesis because addition is associative
7x-10 + 6x+8
combine like terms
13x-2
13x-2 is the answer
34.12 thirty four=34 and=. twelve hundredths=.12
X = games won
y = games lost
x + y = 72
x = 2y + 15
2y + 15 + y = 72
3y + 15 = 72
3y = 72 - 15
3y = 57
y = 57/3
y = 19 <=== lost games
x = 2y + 15
x = 2(19) + 15
x = 53 <=== won games
