What is 3x plus 7y equals -16 -x-y equals 4?
y = -1 and x = -3
What is the answer for the ordered pair form x plus 7y equals 39 3x minus 2y equals 2 using substitution?
If you mean: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
How do you solve 12y-4 equals 7y plus 16?
12y - 4 = 7y + 165y = 20y = 4
What is the area of a triangle formed when the line 3x -7y plus 4 equals 0 meets the x and y axes?
If: 3x-7y+4 = 0 then 3x-7y = -4 The intercepts are at: x is at (-4/3, 0) and y is at (0, 4/7) Distance of x from the origin: 4/3 Distance of y from the origin: 4/7 Area of the triangle: 1/2*4/3*4/7 = 8/21 square units
4-16x plus 28y equals?
4(1-4x+7y)
3x plus 7y equals 37 and x equals 3 then y equals?
4
If T equals 3x plus 7y what is T when x equals 4 and y equals 6?
T = 3x + 7y; x = 4; y = 6T = 3x + 7y (substitute 4 for x, and 6 for y)T = 3(4) + 7(6) = 12 + 42 = 54
Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
What is 3x plus 7y equals -16 -x-y equals 4?
y = -1 and x = -3
What is the order pair for x plus 7y equals 33 and 3x - 2y equals 7?
The ordered pair is (5, 4).
What is the answer for the ordered pair form x plus 7y equals 39 3x minus 2y equals 2 using substitution?
If you mean: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
What are the ordered pair to equation x plus 7y equals 33 and equation 3x-2y equals 7?
x = 5 and y = 4
How do you solve 12y-4 equals 7y plus 16?
12y - 4 = 7y + 165y = 20y = 4

4-16x plus 28y equals?
4(1-4x+7y)
7y plus 8x plus 4 equals 20 plus 8x?
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
3x plus 2y equals 4 -3x plus 4y equals -10?
(2, -1)
