This is the solution to this system of equations...
y = x + 4
y = 2x + 5
What is (1, 3)?
r + s = -6
r - s = -10
x = 4y
2x + 3y = 22
The sum of two numbers is 104. Their difference is 68. What are the numbers?
x + y = 104
x - y = 68
What are 86 and 18?
y = 3x - 2
y = -x - 2
8a + 5b = 9
2a - 5b = -4
y = x - 2
3x - y = 16
y = -3
x = 5
2x + 3y = 6
3x + 5y = 15
y = 3x - 1
7x + 2y = 37
y = (1/3)x - 3
2x - y = 8
2a - 4b = 12
-8a + 16b = -48
3s - 2t = 4
t = 2s - 1
The dimensions of a rectangle whose perimeter is 78 inches, when the length of the rectangle is twice its width.
2w + 2l = 78
L = 2w
What is 26x13?
When the equation looks like this...
5x + 10y = 15
It is in this form...
What is STANDARD FORM?
This is a VERY special case...Examine the system....The solution to the system of equations:
y = 3x - 3
y = 3x - 2
What is NO solution?
These lines have the SAME slope so they will be parallel!!!!
(1/3)x + (1/4)y = 10
(1/3)x - (1/2)y = 4
t + u = 12
t = (1/3)u
