Solve for Unknown Variable
5(x-2) -6 = 6(2+x) + 5
x=-33
(3x-6)/12 + (4+x)/6 = 1/3
x = 2/5
Create an x & y table for the equation y=1/3(9-x), using the values for x of -1 to 1
x: -1, 0, 1
y: 10/3, 3, 8/3
-5(x+3) = 8y
a) Express x in terms of y
b) Find the value of x when y = -1
a) x = -8/5y - 3
b) x = 23/5
6x - 0.2(10 - 8x) = 5.6
x=1
1/4(x-4) = 1/4x - 1
Infinite Solutions
Complete the chart for 4x + y = 8
x: 2, ? , ?
y: ? , -8, -12
x: 2 , 4 , 5
y: 0 , -8, -12
(2x+3)/4 = y
a) Express x in terms of y
b) Find the value of x when y = 1
a) x = (4y-3)/2
b) x = 1/2
Leave as a fraction: 3(5x - 4) = 20(2 + 4x)
x= -52/65
Yankel wants to spend his Chanukah vacation biking at the beach. The chart below shows the relationship between the rental hours and total cost of biking.
Rental Hours (h): 0, 1, 2, 3
Total Cost (C): 45, 55, 65, 75
a) Write a linear equation describing the relationship between the rental hours and total cost of biking:
b) If Yankel decided to rent the bike for 8 hours, what would be his total cost?
a) C = 10h + 45
b) C = 125
