Gary is comparing carpet companies. Company A charges $40 plus $5 an hour and Company B charges $20 plus $15 an hour. Create an equation
40+5x = 20 + 15x
3x-4=10
x = 14/3
-3(4x-8)=-36
x = 5

6(6y +6)-5 = 1+6y
y = -1
l 6x - 4 l + 3 = 11
x= 2 and x=- 2/3
x/4 +5 = 6
x = 4
-10n + 3(8+8n)=-6(n-4)
n = 0
-12(x-12) = -9(1+7x)
x=-3
3(x+5) = 15
x=0
